Add "head butt" to that list. I taught Patrick how to do and say that last night, which was funny and seemed like an ok idea, until I didn't see it coming and he knocked me right in the nose hard enough to make my eyes water and my sinuses sting. He has a head of steel, apparently. To those of you (who?) who haven't seen it lately, it's on the larger side, too. Trust me, it hurts.
