When I was a CP at Mouse Gear, I checked out Jim Gaffigan. He was with his family and as a CM I could not geek out in front of him. It took all of my strength and willpower to keep me from screaming "Hot Pockets!" or "Bacon!"
This next celebrity sighting is a bit more substantial and personally fulfilling. When I transferred over to Splash Mountain that summer, I was at the first dispatch station and I got a call from a manager that a VIP was coming down and that I should be ready to keep a log open. The first thing I see is this large man with a recognizable Brahma Bull tattoo on his arm. "Holy #$^% it's The Rock!" my mind kept telling me. Keep in mind I watched wrestling religiously when he and Stone Cold had their big feud so this was a pretty big deal to me. He was also with his family and I noticed his daughter wearing a Birthday button, so I tell her "Happy Birthday" and she says thank you back; his wife also thanks me. The Rock takes a look at my name tag and at first doesn't say anything, but when they were getting into the log, he shouts back "Thank you Brian!" Needless to say, I nearly freaking fainted. I might have been playing it cool on the outside, but my inner teenage wrestling fan version of myself was about to burst out like Alien. And that experience could have ended right there and I would have been content. When they came back around, I was thankfully still at that same station. They got out, I asked if they had fun. The daughter, with a huge smile on her face said "It was awesome!" The Rock and his wife both thanked me. The Rock came over, shook my hand and said "Have a good day Brian." They left with their guide and that was that. If I were to have been struck by lightning right there, I would have died a happy man.
