Margarita machine Puns

I was eating with my folks last night. My dad wants to split a margarita with my mom. So he asks the waitress if he can order one. She then tells him that the freezing machine is down and he can't have one. I said, "Well that's not cool." The waitress rolls her eyes, and a tear streams down my dads face as he congratulates me on the joke. I've never been so proud.
