What's the most embarring thing your child has ever done/said?

i was in the fitting room at a department store with my 3 year old daughter and i was trying on pants. she saw that i was wearing a thong and she blurted out loud, (really loud,) "mommy, your underwear is in your bottom!!" "you need to get it out!!" i was super embarred. But i couldn't help but laugh.
