I have lots of foolish moments, but I can only think of one at the moment.

A few months back, I was in a supermarket and it was a horrible rainy day, so the floor was wet where everyone was walking in the mud and rain. I was with my dad, and we were along the back of the supermarket where about 3 aisles could see us. Anyway, I was wearing boots which didn't have very good grip, and with the wet slippy floor I managed to fall over, but instead of just falling to the floor, I landed half in the metal shopping basket my dad was holding. My dad dropped the basket to the ground, which meant it made a very loud noise.
By the time I got up, I looked around to see quite a few people looking at me... It was very funny though, and I couldn't stop laughing for ages afterwards
