LOL I would be down with an immaculate inning.
A 1-2-3 inning, of course, is the preferred outing. But I can usually stay fairly calm as long as the tying run does not come to the plate, where one swing can blow the save. In a 1 run game, the tying run automatically comes to the plate, so those are pretty much always nerve wracking no matter what. With a 3 run lead, I can deal with a base runner.
The bases loaded crap, where the 1/2 inning takes 20 minutes (or more), is unbearable.
