Jared: In Asylum, the episode Asylum in the first season, Smallville was shooting right next to Supernatural, and we had this scene, we were just driving up in the Impala, and so between every take we'd drive back, and we happened to see Tom, he was walking to his trailer, so we honked or something, and he's like, "Hey!" So we came over, we started chatting, and we're like, they're calling for us, they're saying action over the walkie.
So he just hopped in the car, and we drove in, and no one knew, no one knew that he was there, so we just drove up to set, out gets Jensen, out gets me, out steps Clark Kent. Everybody's like, "What the heck... Who... Who's that guy you're... That's Tom!" We had a laugh, but I don't know why it didn't make it to the [gag reel]. I think it was before we knew we would go for a full season, so we didn't know we were gonna need a gag reel, or have a gag reel. So it was lost forever.
Misha: And probably also you would have had to pay him a million dollars.
Jared: He owns the rights to the show now. For that shot!
