Nick: a lamb, or a sheep. Ever listened to "Dont Want You Back"?? You'll hear his little maaa-ing. Definatley a sheep. Hey!! He could be Lambchop's bf!!
AJ: a poodle. One of those miniature ones. Ever notice how they are always humping things?? Totally AJ.
Brian: a monkey. They are bossed around easily and dress up in whatever (probably would pull their pants down too). And they are soooo funny. Not that that has anything to do w/ Brian. He just looks like one.
Kevin: a tiger. If you listen to "If You Want It To Be Good Girl" at around 1:33, you'll hear a little growl. Its probably AJ or Nick, but I gave it to Kevvy Kev.
Howie: a bird. One of those little high pitched ones. Nuff said.
