On the Conan O'Brian show on late night NBC they once sent Andy Richter (may he rest in peace) to a new age conference at some hotel.

One Indian guy was espousing urine therapy. After several cheap jokes at the dude's expense, they cut to Andy talking to some people at Taco Bell. He was asking things like, "Have you ever considered urine therapy..." to people who were eating their burritos and whatnot.

One guy answers something like, "No thanks I'll stick to my tacos."

They cut back to Conan in the studio who quips, "I'm sure Taco Bell really appreciate that kind of advertising. Taco Bell -- it's better than drinking your own urine."
