Poor Jason Segel. He was only there for an interview and to talk about being naked on camera, not knowing that Ellen DeGeneres would pull such a silly prank on him!
Well, he should’ve seen this coming because she does it ALL the time. LOLz!
Seriously, she’s scared and pranked more celebs on her show than we can count on our fingers and toes!
Such a terrible thing to do to the nervous man, but it’s HIGHlarious!
Maybe the next time he’s on Ellen, he’ll be more prepared.
Watch it all go down (above)!!
