What's the most embarring thing that you've done in front of family?

okay so this is a pretty dumb question, but i got bored, so i decided to ask. You know it's really easy to get embarred in front of friends, boy/girlfriends, co-workers, etc; but when it comes to family, you usually wouldn't get too embarred doing things that would normally turn you RED in the face in front of non-family members. so my question is what is one (or more) thing(s) that you have done in front of family members that were super embarring? mine is when i was practicing my "y talk" in front of the mirror and my dad walked in and i didn't realize it, so i kept on going until he told me goodnight! mortifying!!!!!!!!!
