Lyrics
Jesus: It's time to put hard times behind, get all the bad things off your mind. He's feeling good, She's feeling good, We're feeling good, yeah. Just hanging out, Just having fun, we're number one, just hanging out, just having fun.

Chorus: I'm a dude, he's a dude, she's a dude, we're all dudes, hey. x2

Jesus: There's nothing better than your friends, there's no problem you can't win, someone who's always got your back, not giving about this and that. Just hanging out, just having fun, we're number one, just hanging out, just hanging out, just having fun.

[Chorus x2]

Jesus: It's all about meeting new faces, smile on your face and you can't erase it, partying on, it's going on, partying on to the break of the dawn. It's tine to put hard times behind, get the bad things off your mind , just hanging out, just having fun, we're number one, just hanging out, just having fun. Just hanging out, just having fun, we're number one. "Uh, wait what are we doing now? Uh, yo we're breaking it down... Rock on, dude., haha.
