My parents never go out. They've lived in Plano for 20 years and their idea of a night out is Chili's.
I bought them tickets to a show at Addison Improv for their anniversary. They were skeptical. My mom kept asking "is it going to be vulgar?" (yes, a little).
But they LOVED it. My dad was crying laughing. My mom was covering her mouth trying not to laugh too loud. They talked about it for a week straight.
If you need a gift idea for people who "don't need anything" — comedy show tickets. Works every time.
