Most embarrassing thing that happened to you at a con?

Just thought I would start a new thread people can post on when they are bored. I am sure everyone has at least one awkward convention story to tell. Lets hear them!

This one requires a bit of a back story to fully understand the humiliation factor of it... Last year i attended a martial arts/japanese culture academy for 5 months, I was the oldest student on campus and quickly earned then nickname Jiji or Aniki depending on the situation, I held the position as Senior gamer and all-around tournament fighter champion. Anyway the whole school goes off to the local con, and I immediately head for the old school gaming machines to kick some ass, lo and behold I locate a Sega dreamcast running Soul Calibur, I issue a declaration of challenge to all the nearby onlookers, but the only one that dare play against me, is the schools youngest girl, a complete gaming noob... We sit down to play a few rounds, and I get my ass handed to me consecutively even getting beat with a perfect in the final round as i pick my favourite character nightmare... humiliation was complete and I spend most of my time playing space invaders and pacman on old arcade cabinets during the rest of the con. (on the upside I beat her in DDR although I had never tried it and she was a veteran in that department)

The most embarrassing thing that happened to me at a con? It was the last day of the New York Anime Festival (aka New York Comic Con). I'm walking around in the Dealer's Room (more like Dealer's FLOOR, but anyway...) and guess what happens? I LOSE MY SPENDING MONEY! It must've fallen out of my pocket; the costume I was wearing didn't have deep pockets. I'm lucky there was an ATM nearby. I am not making that same mistake twice.

I was talking about my old OC for Bleach, and I was explaining to my friend that Shunsui Kyoraku was the "adopted father" and I was explaining why I chose him (Because he's awesome wasn't enough for her), and I had eaten A LOT of candy....so I was hyper, and there just happend to be an amazing Kyoraku cosplayer right there next to me, listening to me go on and on about it, and he was supremely amused. So I turned around, saw him, and screamed like a little girl. Needless to say, I avoided him for the rest of the convention, even when he offered me a cookie. T-T I felt horrible for ignoring him, but I was so embarrassed. Hahahahaha~

i went to a con as death the kid...and i only had 7 hours of sleep total the last two days so i didn't notice i was half way in the large girls bathroom until i felt glances of death staring at me >< i was going to say why are all your breasts unsymmetrical...glad i didn't lmao!!
