Little Johnny comes home with a homework paper to do. He asks his dad to help him write about the difference between theory and reality. His dad says, "Go to your Mom and ask her if she would sleep with another man for a million dollars. "Little Johnny does as he is told, and Mom says, "Well, yes, I suppose I would." His dad then says, "Now go ask your big sister if she would sleep with another man for a million dollars. "Little Johnny does this too, and Sis says, "Yes, I suppose I would." Little Johnny and his dad then sit down, and Dad says; "Now son, you've learned the difference between theory and reality. In theory, we're sitting on two million dollars. In reality, we're living with a couple of whores."
