Comedy.
Blowing your nose at work.Surrounded by other people who happen to be talking to clients on the phone. Realizing you've got a lot coming out. Realizing you've been blowing your nose for a bit of time now. Realize you're kind of loud. Pause. Throw out tissue. Only to get another one because you're not done. Continue blowing your nose. Out of the corner of your eye, see a co-worker, who is still on the phone, now looking at you. The humor of the situation causes you to laugh. But then you realize you have to stop laughing and finish blowing your nose. Because you've just learned that you can't blow your nose and laugh at the same time.
