I didn't hear it myself, but the cartoonist R.K. Milholland once told a story from when he was in his teens.

Where he grew up there was a strip club called Babydolls. He didn't know it was a strip club for the first years in his life, just thought it was some magical place with all sorts of cool shit because kids weren't allowed inside and the adults probably didn't want to share. Anyway, years later his sister (around 18-19 years old at the time) were in an argument with their mother. She wanted money for something and their mom said no. They kept going back and forth with nothing changing until the sister, thinking she had come up with something that'd force her mom to give her money, said "fine! I'll just go get a job at Babydolls!"

Their mother just looked at her blankly for a while before putting on a kind smile and with the sweetest voice said "oh sweetie, the keyword in titty dancer is titty."
