Pretty much everything in Homestuck is real. Homestuck is a documentary.

Homestuck: the only archive needed for future generations. You got your Tab Soda, your ICP, your fruit gushers, wax lips, scotty dogs, your Guy Fieris, scary Wolf heads, Charles Duttons, Rufio!, your Snoop Dog and Nic Cage, your Faygos, etc..  What else do you need?
