I found the entire Al Roker run pretty unwatchable. I think the one with the cast from My Name is Earl was probably the worst one.
Was that the one where they basically play in character, and got "Celebrity Hot Potato/Paula Poundstone" levels of not caring about the game?
Now, the whole "in character" thing, if done right, can be entertaining...see: the weeks on Password Plus when they did it; also, truthfully, Jon Bauman was a decent game player in Bowzer get-up.
As for which one I'd skip? How about the most recent one (I won't dignify it by naming the teams...actually, seeing that That and wrestling have been the only celeb weeks on Harvey Feud re-enforces its "white trashy" image...)
