7Saturday Night Live (2005-2013)
If Bill Hader’s relatively small roles on South Park just aren't cutting it, then boy, then there's this great show that would be just perfect. It’s called Saturday Night Live. There are sketches, celebrities, and political satire like you wouldn’t believe. Maybe a bit less political satire than some
of the more recent years, but it’s definitely still there. SNL is where Bill really got the time to grow into a professional writer and performer. A great fast-paced, creative environment that practically forces the writers and performers there to sink or swim. It’s hard to imagine that Barry would even exist without Hader’s time spent at SNL.
