Holy CUMmunion

Alright, listen up, dummy. The joke plays on the words "holy communion," a Christian ritual, and replaces "communion" with "CUMmunion", implying the priest had some illegitimate kids. Get it? I bet you don't, but you better fake laugh so you don't look like even more of an idiot than you already are, which is saying something since you read jokes explained by a bear.
