I thought the puzzle time out during the gurney carrying challenge was fine - but give them at least a half hour, especially if the teams are so far apart and you're trying to "fake" an equalizer.
Timing out on the puzzle before the swim? Uh uh, you stay and complete that challenge until Teej comes out and tells you that you are the dummiest dummies who ever dummied for not figuring out that Slot A goes into Hole B. A Phil Keogan guest appearance in this case would also be fine.
And its been 20+ years, but it's still TOO SOON for a Bills joke.
