Goof Off

You know how some kids can't resist goofing off in front of the camera? 
Mugging, if you will? 
Hamming it up?

Yeah, well, some of us never really grow out of that...

"Doh-de-doh-de-doh...  I love playin' with my hoodie!  CHEESE!"

"Yee-haw!  I'm a-ridin' a buckin' broncho!  Giddy-up, little doggie!"

"Look, Ma!  No hands!  (Haw haw haw.)"

Real mature.
