"Cockadoodledoo"

From my friend Brendan Mooney: 

Grumpy St Peter, standing at the gates of heaven, says to naughty Tommy

"You can't come in, you've been real bad"

Tommy says, "How bad?"

St Peter says: "Well, for starters, Tommy, you did not believe in God, drank too much whiskey, swore and cursed...need I go on Tommy?"

Tommy shrugs and says: "Oh that's too bad, but in my defense I only have one thing to say to you Peter".

St Peter says: "And what is that, Tommy?"

Tommy says: "Cockadoodledoo" 
Luke 22:34
St Peter says: "Eh, yeah, I forgot about that...Welcome home!"
