Don't remember the season the episode is in, but it was because Bob and Linda were having a napkin throwing contest and turned it into a wet dart contest called NARDS (I think) and Teddy and Mort joined in. Teddy tried to make a shot but missed and he blamed Bob for ''breathing too hard''. Might be my favourite scene from Teddy, next to the Christmas episode where he got trapped in a snare Louise rigged the fridge with.
