The best sketch shows are from a group of tight-knit people who've worked together for a really long time.
There's always something interesting about comedy teams that have the exact same energy. The one time I really noticed that was Will Ferrell and John C. Reilly in 'Step Brothers.'
You see people who are disenfranchised elsewhere coming to Comic Con and making lifetime friends. I love seeing the outcasts of society all bonding together.
