Tell a joke to your group minutes before you all tee off (and try to let other groups watching on hear you). It puts everyone in a great mood and you get the round started laughing, becase company outings are meant for fun, not competition. You do that enought at work, it's time to have fun with those you fight with all day long. (Just be sure the joke it clean...not too short like the "my mamma is soooo fat.., but an anicdotal that has a good setup and killer punch at the end.)
