Most embarrassing thing to happen to you at a FIRST event?

During the finals of the 2015 MN 10,000 Lakes Regional, I rolled my ankle when dancing in front of the arena to YMCA and fell to the floor.

Of course everyone was watching...

Saying my own team number incorrectly during alliance selection.... twice.

I was nervous and hungry and I stuttered.

Not my embarrassing moment, but my son's during an off-season event a few years ago.
He was the driver and captain of the team at the time, (he's in his third year of college studying electrical engineering now, and he still brings this up)

It was one of those off-season events where teams bring more than one robot and have rookie teams (or non-official teams just starting out) drive the spare robots at the event for exposure, experience and practice.

One experienced team brought a spare robot that was just a driving chassis and bumpers, it didn't do anything else. The numbers they stuck on it was a mix of the experienced team's numbers, so if the experienced team number was (just for example): "1234", the spare robot had a number like "1324".

A rookie team just starting out was driving "1324" during the competition doing the best they could, but was seeded last.

When my son was picking the alliance for finals, he wanted to pick "1234" but picked "1324" instead, and realized his mistake when picking was done.. we held our own for a while, but I don't think we got past quarter finals.

In his defense, alliance picking started at lunch time, and the rest of the team went to get lunch, so he had no help with picking, and he was picking on the fly.

He made the best of it, he still had fun at the event, but like I said, he still brings up the "Team Brick" debacle.

During MSC for the 2013 season, we were in the middle of the semi-finals against a higher seeded alliance. We won the first match and were noticeably excited. Before the second match we had our alliance meeting and then had our standard "just us" pep talk with myself and our drivers. Right as I finished saying whatever it was that I said, I looked up at the time left in the match before us and caught an errant full court frisbee straight to the safety glasses. Luckily that was the time that Detroit Public Television was there but they missed it.

I didn't quite coach as loud as normal for the next match, that frisbee rang my bell pretty good and my glasses split the bridge of my nose open a little...
