Dinner With Parents - Worst Jokes Ever

I thought of having a threesome, but then I realized that if I wanted to disappoint two people at one time I might as well have dinner with my parents.

Explanation

The joke plays on the idea that the speaker's parents are easily disappointed, comparing the likely disappointment of a threesome to the inevitable disappointment of a dinner with their parents. It's a bit self-deprecating and relatable for people who've had similar experiences.
