Haven't watched South Park for a few years, but Washington's head mentions having hocked his teeth for booze money in Futurama, too. Really, really shitty choice for an example of an unsmashable (so to speak) icon there.

I still think if you wanted to pick out the perfect example of the Dada spirit in sort-of-present-day culture, you couldn't go too far wrong with Mr. Noblet's line from the STD episode of Strangers With Candy: "...and of course, Fidel Castro impersonated Marilyn Monroe and gave JFK a case of syphilis so severe that eventually, it blew the back of his head off."
