'Country Doctor' skit

Does anyone on here know if, in this skit, it's Mark McKinney whose playing the part of The Grim Reaper/Death, or was it just some other actor who wasn't part of the series or maybe someone who was a crew member on the show?

I'd really like to find out whether it was McKinney or not, so if anyone here has any helpful info on this I would greatly appreciate knowing about it.
