Drunks at the Zoo
Two drunks wander into a zoo after midnight, and end up standing in front of the Lion cage.
The Lion, who was asleep, hears them approach his cage and wakes up, of course. Not wishing to be stared at, he leashes out a couple of mighty roars.
One drunk starts to wander off, but the other drunk grabs his arm and says, “Whaddaya leaving for, Herbie? The picture’s just started!”
