"Get Fuzzy" is a daily comic strip about a guy named Rob Wilco and his pets Bucky Katt (a Siamese cat) and Satchel (a mastiff). In the "Get Fuzzy" world created by Darby Conley, the humans can converse with the animals who also use the phone, abuse Rob's credit cards, and generally act human.
Bucky has a relative named Mac visiting from England, and in today's Sunday edition of the strip, Bucky was asking him about the manliness of the English.
Bucky: "OK, so they're nice and butchy in Manchester. Are they foppy everywhere else?"
Mac: "EVERYWHERE ELSE? In the entire coontry? Are you havin' a laugh? IS HE HAVIN' A LAUGH?"
This could be the first pop culture reference to Ricky Gervais' TV series 'Extras' in which Gervais played an actor named Andy Millman. This past (and last) season of 'Extras', Andy had his own hit TV show in which his character had the catch-phrase "Are you havin' a laugh? Is he havin' a laugh?"
In the universe of comic strips (some of whose characters have doppelgangers in Toobworld!), O'Bviously they watched 'Extras' on HBO in the Wilco household. Or Mac saw it on BBC2 while he was back home.....
