What is the funniest group of challenges?

Which challenge has the funniest cumulative results from all four of them?

My vote would have to go with when they get massages in "Fe-Mail". I don't think there's a single line in that one that isn't extremely funny and can bring tears to my eyes from laughter no matter how many times I watch it. Murr turning his head around, his story about roundhousing an entire family, the "massage my bald" request, Sal's apology for being sticky and shaking like a ghost from laughter, Q dropping his robe in front of the masseuse, and Joe getting bent like a pretzel and asking for permission to wiggle are just a few of the classic lines and moments.

Runner-up would have to be when they work in the liquor store in "Snow Way Out". The only gripe I have with that one is that the "featured moment" of Q throwing the ping pong balls at the large black man isn't all that funny. But everything else (Murr speaking in falsetto, taking beer out of the guy's cart, Sal charging at a customer, Q's wife/husband looking like a pork chop, Joe turning two customers against each other with the same story) are some of the best the show has done.

What other challenges are up there with the show's funniest?
