What is the absolute dumbest thing anyone has ever said to you, and what was your reaction?

Was once having sex with a girl who had a bimbo fetish, so she was pretending to be dumb af. When I announced that I was gonna cum, she looked at me all confused and said the legendary words “huh, you’re gonna cum inside of me? Aint I way too stupid for that?”

That was my first and only orgasm while laughing.
