Most embarrassing thing that happened to you at a con?

Not really embarrassing but surprising: Was at Nakakon '10 when a kid collapsed in front of me in seizure. Everyone else just kept on walking by, even stepping around the kid. Me, I went all "NOT ON MY WATCH, KID" mode, immediately grabbing a pillow and yelling for help. Took three minutes for con helpers to get there, nearly ten for ambulance. Ambulance guys were impressed that I dropped what I was carrying to help a complete stranger. Kid got to keep the pillow I used on him to make sure his head didn't slam into stuff. The screwed up thing was that people just kept on doing what they were doing. Probably thought the kid was freaking on ramune soda and pocky.

Well, I'm a cross dresser and I thought it'd be funny to go into the girls bathroom in my sailor fuku and take a leak. I kind of look like a girl so nobody said anything. A couple of girls that were washiing their hands just giggled. Not really embarrassing but it's a fun little story of mine. I'm sure I broke a law with my little mischief but hey, -Innocent- fun.

I was in my Hatsune Miku cosplay and i was walking around then i dropped my leek, so i bent down to get it then when i stood back up i tripped over my hair, and fell face first into Misa Misa's boobs :/

I was jumped on by an Al Elric randomly because I was dressed as Edward. It was also a girl and she yelled BROTHER!

I read a yaoi manga from the adult section of a con library not knowing it was yaoi until I was a quarter of the way into the book and noticed the distinct lack of female pronouns in the narration. Once I took a closer look at the cover and noticed the little bit of text labeling it as yaoi, I said, "OH MY GOD!" and promptly returned it. Needless to say, I then understood why the librarian looked at me funny when I requested it.

not embarrassing for me but hay i went to the euro gamer expo in london 2 years ago with my gameing class and saw 'guitar hero wor' being played so i walked over iching to have a go then i heard a few of my class mates saying that i must suck im no good at anything ect then one of the guys giggleing away says 'ill challange you to it but it has to be on expert' i say yeah we get to it and he chose 'fury of the storm' he asks me what to base the score on we agreed on percentage me with 97 percent and him on 70 with 2 fails the endless hours pays off!! ^^

It is not really embarasing for me, but it would be that since 2 years ago I have been going to cons, as genderswaped Touhou characters. Until now: Patchouli Knowledge, Reisen Udongein Inaba, Shaimeimaru Aya and Yuuka Kazami.

I was cosplaying Heather from SH3 at a con, and these two guys stopped me in a hallway and asked me to do her "sexy beam" or whatever - I had absolutely no idea what they meant because I've never played that feature, and I ended up getting mad and embarrassed, stormed off passed them, and later my friend told me the guys were really just asking me to do the pose. D: I had no clue, felt horrible. Still do. lol

I had two that I could recall when I was walking too see a movie I got grabbed from my group by some random girl and dragged me to some type of ballroom dancing I was super embarrassed. Another was when I was in a game tournament going on at the convention got too the finals then lost because I committed suicide five times in a row at the start because I was mad that I couldn't make a jump I have done all the time for some reason I got stuck on trying to make this jump.
