Loser idiot boy: Omg! have you heard of Pro-Activ?
Pimpely faced person: It's a part of growing up, not that you would know!
Random guy who pops up: Snap Crackle and Pop!

guy: Yo mamma is so fat she is like a whale! hahaha
other witter guy: Yo mamma's so fat i burnt my ass on the light when i was fucking her last night!
Guy: ... *punches other witter guy in balls to try and prove his manlyness after being completly owned*
