Okay, to get it you kinda have to know John Cena. He's a big league wrestler in the WWE, lots of fans hate him because he's kinda the superman of WWE: rarely ever loses, when he does it's to make someone else look invincible, only to have this new would-be villain taken down next week and make someone ELSE look awesome.

He's got a TON of merchandise and kids go apeshit for him. Because of that, many older wrestling fans (who remember him as kind of a jackass with a bad attitude before he turned hero) aren't really fans of the guy and love to mock him.

But one of the gimmicks they have for Cena is listing out a bunch of seemingly ordinary things and then suddenly blaring his intro music and yelling "AND HIS NAME IS JOHN CENA!" (bah badah bahhhhh!)

There's a really funny (fake) prank call bit using his gimmick, I'll share the link:

EDIT: Also, to the people who downvoted this guy instead of just answering him, screw you. Be cool to people.
