You heard it right. The same guy who brought us such gems as the 10 commandments of driving, the realization that unless you are a Catholic, you do not belong to a real church and modified the Good Friday prayer to include the conversion of Jews to Christianity now say "Condoms are bad, mkay." (apologies to Mr. Mackey)
I have to love Jon Stewart's response. None other is needed. "The pope went on to say that smoking curses cancer, and that if you are looking for a quick morning pick me up, try heroin."
Sometimes stories write themselves.
