The Bloody Mary one was shit.
For the benefit of Xero Limit whatever, Randy got caught drink driving and thought his alcoholism was a disease, some religious guy found a statue of the Virgin Mary was bleeding out of its arse and everyone thought it was a miracle so they went and worshipped the statue and hoped it would heal them if it bled on them, then Pope Benedict shows up and realises the Virgin Mary is bleeding out of her vagina, and that's no miracle.
Quite terrible episode, wasn't really funny at all - just offensive.
Also,

@ Cartman's big speech about everyone comparing him to Family Guy
