Before Shawn arrived, when they were talking about him, I thought he would look something like Kenny on The Middle or Harry Knowles, basically like a big guy with long, scraggly hair, who appears to constantly play video games. That was just the picture I had in mind.
I would have liked a Dave Foley type actor but the actor from B99 was a good choice for the character ... very straight laced.
I was a little disappointed in Adam Scotts character. I kept wanting to love his performance but I just didn't. He did really well in his acting, but for some reason, it didn't entertain me.
Both those characters fell a little flat for me, but maybe it's because the main characters in the show are so fun and colorful that the guests feel more like a "remember me from that other show" type appearance rather than a character.
