What was the most embarrassing moment of your life?

Of my life? Hard to say, today? I went to get a pizza for dinner and in the car park I came across two teens doing something weird. I think one was trying to get changed n the passenger side, (At least I think that's what he was doing. he wasn't wearing underwear.) And his mate was filming him from the outside of the car and even opened the door. They saw me and stopped what they were doing and rushed to get dressed. But then went into the same Pizza shop. So they didn't know what I saw but knew I saw something and were trying not to make eye contact and I was trying to not look at them also... The Pizza couldn't come quick enough.
