The Whitest Kids U Know: what a buncha troublemakers (http://www.youtube.com/watch?v=QEQOvyGbBtY) :o
I think it was more of a homage. Really the original message from the Kids was a joke being played on one clueless guy, Bud's commercial shows it catching on and becoming a fad, almost a parody of internet fads itself.

http://en.wikipedia.org/wiki/Whitest_Kids_U%27Know is apparently a "regular" TV show (sorta like a current-gen KITH?) on "Fuse TV" (http://en.wikipedia.org/wiki/Fuse_TV) channel or something... Wow I miss out without cable ;)
