I've been meaning to post this. It's a paraphrase from a commercial about "good sandwiches".
dad: "Hey, Jeff!"
jeff: "Dad? What are you doing home so early?"
dad: "I'm just . . . What's that?"
dad: "Jeff, do you think I'm stupid? That's a bad sandwich!"
jeff: "Dad, I... I... I learned it from watching you, Dad! I learned it from watching you!"
Narrator: "Bad sandwiches can happen to anyone. Make sure you talk to your children about good sandwiches, like the ones at [insert whatever store it was]."
