Third one memes

A doctor is telling three women what they are addicted to.

He says to the first one, "You are addicted to money, you named your daughter Penny."

He says to the second one, "You are addicted to food, you named your daughter Candy."

Then the third one whispers to her son, "Come on, Dick, let's go."

An infinite number of mathematicians walk into a bar. The first one orders a beer. The second one orders half a beer. The third one orders a fourth of a beer. The bartender stops them, pours two beers, and says, "You guys should know your limits."
