A little boy comes home from school and tells his father that his homework assignment is to find out the difference between “potentially” and “realistically.”

“Easy,” says his father. “First, ask Mom if she’d sleep with the mailman for a million dollars.”

The boy runs off, then comes back and says, “She said yes.”

“Now go ask your sister the same question,” advises the father.

Again the boy runs off, and again he comes back and says, “She said yes.”

“So, potentially, we’re sitting on two million dollars,” replies the father. “But, realistically, we’re living with a pair of whores.”
