The Playboy Bunnies

Three rabbits escape from a testing lab. On their first night out they find an entire field full of carrots. They eat themselves into a stupor and sleep throughout the night.

The next day they find an entire field full of female rabbits. They all do what rabbits do best, and the trio sleep throughout the night.

The next morning, the rabbits get to talking.
"I'm gonna go back to that field of carrots," says the first one.
"I'm gonna go back to those cute little girl rabbits," says the second.
"I'm going back to the lab," says the third. "I'm dying for a cigarette."
