Mine didn't happen AT a show, but it does involve Jim. They came here in 2005 to tour for AYR and someone had mentioned that if I can, I should drive around the Centrium to see if I could catch a glimpse of the buses. Not only did I see them, but Jim walked out from in between them just as I drove by! I squealed "OMG, that's Jim!", (this next part is a bit fuzzy cuz I was so excited) I guess I put the car in park, but I practically jumped out of it while it was still moving, then I went up to Jim while my mom was getting the camera ready. She snapped a couple of pics and as we were heading back to the car, Jim asked if we were coming to the show. I replied "We sure are!". We got in and drove away. Jim smiled at me during the show cuz I'm sure he remembered me, he actually smiles at me every time he sees me...I think he's starting to know my face quite well by now.
Now it may not seem like an embarrassing moment, but every time I think about it, my face turns red and I say to myself "What were you thinking?!?!?!" 
p.s. Those pics that my mom took are non-existent now cuz she neglected to put film in the camera. Needless to say I was right p*ssed and have since gone digital to avoid such an occurance again.

Just remember, if the world didn't suck, we'd all fall off.
