Everyone likes a prank, and when said prank happens to be on a celebrity? Double the fun.

Not to diminish the difficulties that come with being a celebrity, but it’s nice to see celebrities getting pranked and feeling a little anxiety once in a while. And, sometimes the top pranksters are the friends of those celebrities! On this list, celebrities get pranked by the likes of Jason Sudeikis, Dominic Monaghan, Sacha Baron Cohen, Dennis Quaid and The Terminator himself: Arnold Schwarzenegger!

They love each other, and we love them. Welcome to MsMojo and today we're counting down our picks for the Top 10 Cutest Couples on YouTube.
