Little Johnny walks in on his parents having sex and asks, "What are you doing?" His father says, "We're playing cards, and your mother is my wild card."
A week later, Little Johnny walks in on his father masturbating. He asks, "What are you doing?" His father says, "I'm playing cards." "Where's your wild card?" Johnny asks.
His father replies, "Son, you don't need one when you've got a good hand."
Three rabbits escape from a testing lab and find an entire field full of carrots. They eat themselves into a stupor and sleep throughout the night. The next morning, they find an entire field full of female rabbits with no males in sight. They screw themselves into a stupor and sleep throughout the night. The next morning, the rabbits get to talking.
"I'm gonna go back to that field of carrots," says one.
"I'm gonna go back to those cute little rabbits," says the second.
"I'm going back to the lab," says the third. "I'm dying for a cigarette."
