This is legendary and comes from the Chicago con from none other than Richard Speight Jr. (Trickster/Gabriel). This is from my transcript of the whole thing from my report of Richard Speight Jr.'s panel at the con.
"It's not the dog story. I'm so glad something crappy happened on the set so I wouldn't have to tell the dog story. It's not necessarily a practical joke, although I thought it was. I'm doing the scene where I get stabbed. The officer, there's a different guy laughing and it morphs into me. That actor, who's name's Gabriel by the way (laughing) was really nice and had a good time on the set and he said to me when he left "I'm leaving you a little thank you gift back at the base camp. I said great man, nice meeting you.
I go back to base camp and I go to my trailer and in my trailer is my stuff. Sitting on the counter in my trailer neatly folded up are a pair of pumpkin colored men's bikini briefs. I thought "what the hell, what kind of a gift is that?' I get dressed, without the bikini briefs and I'm going to sign out. I've got the underwear and I'm going to the production office to see Adrian and the guys to sign out and I go "you're not going to believe what I found.â€ He interrupted me and said "Oh, by the way man that guy Gabriel he left these for you.â€ Inside was two beers and a thank you card. Well that makes sense. Who the hell put their underwear in my room?
I'm thinking ah, the tall guys. Ha ha, they're lots of laughs. Leave underwear in the Trickster trailer, ha ha ha. So the next day on the set we're doing the Dr. Sexy stuff and I say "lots of laughs guys' and they're like "what?' "Pumpkin colored bikini briefs I'm wearing them right now. You're killing me.' They're stone cold looking at me at this angle (looking down) going (blank face). And I was like, really? Underwear..my bad. Who broke into my trailer and but underwear in there? It's weird. And it was clearly used. It had that wavy waistband. It had been washed a handful of times. It was clearly bizarre.
I did what anyone else would do, I signed my name to it and put it on the production trailer. What am I going to do with it? I find out the next day, somebody comes over to me and says "we know who's underwear it is.' I'm like "really who's is it?' The guy pointed in the other direction andâ€¦it's Misha. (room explodes in laughter). He's like "That was my underwear.' "Why is it in my trailer?' (Misha says) "I spilled soup on myself at the warehouse all over my wardrobe and I had to switch wardrobes and I spilled soup down my pants, so I happened to have an extra pair of underwear and I put it on. " I said "Pumpkin colored bikini briefs?" (Misha) "It was the last pair I had." (Richard) "Why would you have that pair?" He said "They were a gift from a fan." (Huge laughter from the crowd again).
The rest of the story goes that the wardrobe department found them covered in his trailer and washed them and put them in his trailer not knowing who else would wear pumpkin colored bikini briefs. Richard finishes the story with this:
"So I went back to the production office, took them off the wall, turned them around and wrote on the back, "This pair of underwear smells like Cas." That's his contribution to the production office.
Sorry, but while I know there is a picture of that underwear out on the production office wall somewhere, I just couldn't find it. So, here's another goofy picture of Misha instead.
Okay, that's a wrap on this season's awards. Got a suggestion of a category and/or prize I missed? Send the suggestion along in the comments or through "Contact Us." If I get enough I can do the "Viewer Season Five Awards." Thanks for checking out my usual warped view on things.
