When I was a toddler, my mom was grocery shopping, and in the middle of a crowd of people, I pulled a tampon out of her purse, waved it in the air and shouted "Mommy, what's this?!"
I still hear about it to this day, and I'm 25.
A lady I worked with was going through the check out lane with her son when he was a toddler.
Her son looks at the cashier lady and informed her "I have a small penis and my daddy has a big penis."
The cashier lady looks at Cat, the lady I used to work with, and said "What did he say?"
Cat just looked at her and said "You heard what he said. Don't make him repeat it."
