I learned this year that you only remember the techs you didn't call. Here are mine:

Should have tossed a coach who showed me up (twice!) after my partner whacked him.
Should have whacked a coach after he made statements like "I can tell where we're at tonight!" and "We're getting screwed!"
Should have whacked bench players for standing up during play after three warnings.
Should have whacked a different coach who also said "I can tell where we're at!"
