Joke of the week that starts out good, but the punchline falls flat, then you realize that the joke is pretty funny regardless...

Two giraffes are screwing a gorilla outside of a bar that a priest walks into. The priest goes up to the bartender and says, “Sir, do you know that you have crazy animals committing sin outside?” And the bartender says, “Is my mother out there again?” The priest looks confused and says, “No.” Then the bartender says, “Oh.” Then they stand in silence for a long, long time. Then the priest says, “Oh, what the hell, give me a damn Schlitz.”
