Funny experiences related to hobbies?

Woot for the first main topic (introductions excluded)! Have you guys ever experienced something strange or funny when it came to your hobbies? Games, conventions, conversations? Mine was during a cosplay event. Thank goodness for changing rooms, we had been assigned areas to change in before and after the event. There was absolutely no problem getting into your costume in your gender-assigned area. Well, the restrooms were another story -- especially for a crossplayer. I had to make a little trip to them while I had some time before the next intermission. Now the restroom stall doors had a foot-high space below, and you can see whether someone was there or not because of the person's feet. I became vaguely aware that the girls' chatter had died down-- and I can hear them whispering just outside. "Should we call for security?" Eh,security? Was something wrong? Confused, I finished my business and eased myself out of my stall to screams. ._.) And they were all looking at me. Apparently, they mistook me for someone who had gotten into the wrong area. My boots and pants weren't much help either.. they were hardly feminine (though it was kodona style). I only gave them a long stare, shrugged and exited the restroom. -shrugs- Have you guys gone through weird situations like this, too?
