Here's one I'll tell on myself.

I was 3 years old and we were moving to the US from Scotland. My sister was 1 and a half, my mother was hugely pregnant with my baby brother. The line at the crowded airport was long and Mom was having trouble keeping me under control while holding my sister. So, she let me roam a little.

I became fascinated with a man in another line. I had never seen a person of color. I went over to him and rudely stared trying to figure this out. I touched his hand to see if he was real.

Then, I yelled at the top of my lungs, "Mom, do you like this chocolate man?"

Soooo, what did you do to embarrass the heck out of your folks?
