Q: What is the best food to eat when you are scared?
A: I scream!
Explanation: People scream when they are scared, I mean, really scared. When was the last time you were really scared? Hopefully it was for something fun like a roller coaster and not for something terrible like a car accident or an earthquake.
“I scream” sounds like “ice cream” and that is what makes this joke funny. Maybe a dish of vanilla ice cream would go well with a Hitchcock film tonight.
