What's the most embarrsing thing you have ever done?

I had my most embarrassing moment of my life , when i went to collect the 1st prize my friend had got , just to be reminded by the presenter about the mistake that it was not for me and i had got only the 2nd prize . It was quite embarrassing for me in front of a sizable gathering . The only peculiar thing was that he also had the same name as me . This happened during a Scouts Camp where me and him were captains of different groups and we had some tasks and competitions that we participated in for which awards were given. When the presenter called for the name , I straightly went towards the dais , only to be reminded about it. It was a sizeable gathering or around 500-600 people . My Friends even now gag me for the same , when we sit and chat about our memories !! That was a nice embarrassment !!
