Poor Kevin. You could tell when he had gotten to old to be on that show. His heart just wasn't in it anymore.
Do you remember that silly series they tried to start starring Kevin and Alasdair as brothers who were abducted by aliens? Klea was one of the aliens, and Les Lye was a Ross-like character in it, too.
Nah, the "Who do you think's in the burgers" was the answer to that.
At this point, Alasdair and Christine would open up their burgers to see a little patch with the Nazi ensignia in them while Barth tries to stuff a bloody Nazi uniform in the trash can. Hilarity!
