In the final skit, the mark's name is Brad. Jamie's "boyfriend" introduces him to Jamie's "wife" as such, but shortly afterwards, she addresses him as "Bart."
When Jamie tries to imitate Sean Maguire's accent, he asks if it was a good Australian accent--but Sean Maguire's British. A fellow TV Tome user tells me that Jamie made this "mistake" on purpose to try to agitate Sean; it can be an insult to mistake a British accent for an Australian accent, and by extension, to mistake a Briton for an Australian. Okay, I'll buy that, especially since Jamie was doing everything in his power to be, well, irritating.
Gavin: (referring to Brad Gluckman) I know he's family, Shannon, but Charles Manson, I'm sure, had a brother as well!
