During the first skit, Jamie's character "Ed" hassles Scott while "Kathy" is in the shower. At one point, "Ed" wants to call "Kathy" out, so he yells, "Joannah!"
I'm pretty sure that Jamie goofed here. He probably meant to say "Kathy," but he yelled out the name of the actress instead. He then tried to cover his mistake by crying out, "Kathleen Joannah!"
