I wasn't going to post mine, but someone else posted a non-disney story, and since mine did occur at another Florida theme park, then why the heck not?
First, you must know that I play ultimate frisbee, and the day before my flight I had a very intense practice. This was only about a month after Christmas and I was not back into full game shape and had not practiced since Christmas, and the result was two pulled quadriceps muscles. Yep, both legs. Needless to say, bending or lifting my legs was painful and difficult. Now, on to the story!
So, my friends and I attended the very first Celebration of Harry Potter in January 2014 at Universal. We had the VIP package which included a private event at the WWoHP, which the cast members of HP attended, although they did not mingle with the (very insane) crowd who stalked them for the whole evening. We rode Dragon Challenge, but as we exited the ride we ran straight into the cast who were waiting (hiding) behind Olivanders, as they were waiting to make an appearance on the stage up by the castle. We played it very cool, said hello and said that we would quietly leave them be so the crowd of people hunting them wouldn't see. Anyway, the only way out of the exit was to walk through them, however we weren't allowed as per the security with them, and there were only closed railings all around us, so we had to climb over/under those to get out. This wouldn't normally be an issue for me, and it wasn't for my friends, however this was two days after my practice I physically couldn't lift my legs to climb over or bend to crawl under without extreme pain. So the only thing I could do was lift the less painful of the two legs and do what I can only describe as a very slow sloth roll over the railing, all the while saying, "Ow," and "No, I'm good!" when one of the guys who plays one of the Weasley twins asked me if I was ok. And then my friend's fiancee had to help me untangle myself when I completed my roll to the other side of the rail.
Let me tell you, if there is one thing worse then embarrassing yourself in front of strangers, it's embarrassing yourself in front of strangers you've idolized since childhood.
