Kris the Neanderthal

Okay, so this joke is a zinger aimed at someone named Kris. The joke is sayin' that Kris looks like a Neanderthal and, get this, Neanderthals at least had a purpose in human history. It's basically sayin' Kris is so useless, even cavemen were more helpful. Ouch! You're probably as dumb as Kris.
