Top 10 Funniest Supporting Character Bloopers on The Big Bang Theory

After Shamy breaks up, Amy decides to get back out there. So, Sheldon follows suit. He enlists Howard and Raj to plan an elaborate scavenger hunt that will introduce him to his perfect match. Amazingly, someone does turn up, and her knowledge of flags, Klingon, and ancient Sanskrit is certainly promising! Actually, scratch that last one. In this outtake, actress Lio Tipton, who plays Vanessa, delivers the line and highlights her mistake almost as if it’s part of the dialogue. In all fairness, if she hadn’t mentioned it, we probably would’ve never noticed. But Sheldon would’ve, and he’d likely have shut the door a lot quicker.

When Penny struggles to get her foot in psychiatrist Dr. Gallo’s door, she asks Leonard to pretend to be a patient and put in a good word. Being a supportive husband, he eventually agrees and, over time, convinces Dr. Gallo to meet with Penny. Only the good doc is one step ahead of her, or so she’d have us think. In the blooper, just as she’s about to call Penny out, her mind seemingly goes blank. After a long pause, actress Jane Kaczmarek buys herself a little more time with a witty adlib that causes everyone to break. We wonder what Dr. Gallo would prescribe for this short-term memory loss.

We’ve all been there. You’re so mad or impassioned that the words just don’t come out. Well, that’s kind of what happens here. President Siebert is beside himself following Amy’s outburst at the Fermilab physicists who are taking credit for her and Sheldon’s work. So, he calls her and Sheldon into HR to discuss the incident and damage control. Only, like any of us feeling a strong emotion, he (well, his character) is so mad that words betray him. Still, his emphatic finger-pointing tells us all we need to know, plus it makes everyone chuckle. It brings some much-needed levity to an otherwise pretty intense conversation.

If we know anything about Beverly Hofstadter is that she’s meticulous about everything. And if you tell her you’re showing her your lab at one o’clock, you’d better be ready on the dot. Perhaps this isn’t a quality actress, Christine Baranski shares with her on-screen counterpart. In this outtake, Baranski enters the room, interrupting Leonard and Sheldon’s seemingly serious conversation. Initially, Jim Parsons plays along and greets her. But then, someone runs on with a script to remind her of her cue. Her apology is simple yet endearing but delivered with such spectacular comedic timing that you can’t help but crack up. The audience clearly enjoyed it, as did we.

In this episode, Stuart asks Penny, Amy, and Bernadette for tips on making the comic book store more inviting to women. He reels off a list of changes he's already made, including a questionable choice to install a camera over the "breastfeeding area." In the episode that aired, you can see how creeped out they all are. And Kevin Sussman's earnest delivery only adds to the ick factor of it all. But as we see in this outtake, even he couldn't take himself seriously. His laughter starts a domino effect as the others also start laughing.

Sometimes it’s not just the actors who get confused by who’s meant to be where and when. Take this blooper from season seven. If you recall the actual scene, Leonard, Penny, and Wil Wheaton commiserate at a bar after the latter two get fired. So, we’re pretty sure Wil’s meant to be on the set. Apparently, this director was either looking at the wrong page or maybe even a former version of the script when he tried to offer Wheaton some direction. Luckily, the actor takes it in good humor and delivers a witty retort that breaks his scene-mates, the audience, and of course, us too.

Comedian and actor Bob Newhart was a great addition to “The Big Bang Theory’s” recurring cast. He brought his dry humor and classic deadpan delivery to the role. He also made audiences chuckle when the cameras weren’t rolling. In an outtake from his inaugural episode, the audience can be heard giggling after a director whispers some instructions to the actor. Without missing a beat, he fires back, getting an even bigger laugh. Well, we’d expect nothing less from a comedy giant. In another episode, he also teaches us “couple” and “coward” are practically interchangeable through this hilarious flub. Hey, none of us are at our best when we’ve just been woken up!

In one of the pivotal moments of season 12, Amy and Sheldon’s super-asymmetry theory is proven by the two Fermilab physicists we mentioned earlier. This means they could be on the path to a Nobel Prize if Drs. Pemberton and Campbell don’t get in their way. Well, it seems like their professional rivals aren’t the only ones who don’t understand Sheldon and Amy’s paper, or is it a report? We think we’ll throw this one to actor Sean Astin. Oh, he doesn’t know, either? “Paper” is hardly the most challenging word two actors portraying physicists have to remember. Nevertheless, it’s the one that trips Astin up the most.

We’re not here to talk about how Amy’s mom was originally played by Annie O’Donnell. Rather, we want to focus on what Kathy Bates brought to the role and how she made the otherwise unlikable character a comedic delight. In fact, she’s so good that she even sounds like a pro while messing up her lines. However, this might be our favorite Bates blooper. While Sheldon struggles to bond with his mother-in-law, it’s clear that the actors are having a great time behind the scenes. Parsons is tickled when his scene partner forgets her line. But she quickly hits back, or perhaps we should say, bites back?

Before we unveil our top pick, here are a few honorable mentions.

James Earl Jones Wants a Do-over, “The Convention Conundrum”
There’s a Reason He’s the Voice of CNN & So Much More, the Man’s a Perfectionist

“Access Denied,” “The Military Miniaturization”

Why You Shouldn’t Let Stragglers In, “The Helium Insufficiency”
This Flub Is He-He-He-larious

Zack couldn’t resist a good ol’ catch-up with the science dudes. And bless his little heart, he does try. As we see in the scene that made it to air, he’s meant to mess up Neil deGrasse Tyson’s name. And indeed, it’s funny. But it could have been even more far-fetched, as this gaffe shows. Actor Brian Thomas Smith messes it up so wrong that he practically invents a whole new person. So, it’s hardly surprising that Kaley Cuoco finds it so hysterical she almost chokes on her drink. We imagine that there were a fair few spit takes the first time “Big Bang” fans watched this blooper too.
