Does anyone know if the episodes that aired on PAX were edited or not?

Well, they seemed to be from the same film as the ones TBS used for MF. So, my answer would be yes, they were edited.

When they aired the NBC episodes, I was hoping they would have the opening credits w/ Harvey Korman in it, but they didn't. Oh well...I'm just thankful MF is on at a decent hour now. :)

By the way -- this is for people here who have taped MF episodes off TBS- be thankful you taped the episodes when you did, because they squash the closing credits. But, unlike TV Land, they actually squash the credits to a readable size. They don't squash the credits vertically or some weird **** like that. TBS has been airing unsquashed closing credits for as long as MF has been on that station. :)

They looked the same as TBS.
