Bad meat

Setting: Dad is assembling Max's school lunch. Max notices that Dad is putting sliced deli ham in the bag.
Max: "But I don't like ham. I want turkey."
Dad: "We don't have any turkey."
Max: "I want roast beef."
Dad: "We don't have any roast beef."
Max (sounding dejected): "Well then I'll have ham."
Dad: "Max. I think when I pick you up from school today, you're going to to tell me: 'Dad, this was the most wonderful ham I have ever eaten!'"
Max (pausing): "No, I think I will say it's the most poisonous."
