I definately don't think Gilbert was the best at being a funny guy. I think Mike and Bill were by far the funniest ones but wanted Gilbert (who is horrible at everything he's ever tried) to feel like he was good at something. And, since being a funny guy was his highest ranked event on the team (7th out of 12 participants), that's what Mike gave him. Really just a microcosm of Mike's awesomeness imo.
