Please share a personal embarrassing moment - I'll start

One summer when I was a kid my mother told me to go to the store and get some milk. So I got out of bed, put a t-shirt on, and biked to the store. I picked up the milk, and headed towards the cashier. On the way to the (observing) cashier I noticed that my shorts felt a little light. To my horror and embarrassment I only had my under wear on, and not my bathing suit that I wore for most of the summer. The cashier laughed as I exited the store without buying the milk. If that wasn't enough my mother made me go back to the same store after getting properly dressed.

The sign only says shoes and shirt required. Don't worry about it.
