Back in September, Bill Hader went on Conan and did impressions of several of his fellow former SNL cast mates, including Fred Armisen, Kristen Wiig, and Jason Sudeikis (you can see them all below, although his Armisen impression is also in the clip above). Apparently, this transgression rubbed Armisen the wrong way, and he took his Conan appearance with Portlandia co-star Carrie Brownstein as an opportunity to do his Hader impression to get even. Who do you think did a better job?
