He is so angry over that tailgate, but only in a nominally-curmudgeonly way. Once the culplrit apologizes, he'll clap said culprit on the shoulder and offer him a chocolate egg cream, which has neither eggs nor cream. He'll explain this in excruciating detail before lifting another heavy object.
I want to spar with him at an SCA convention. He'll be all sweaty after the match and proclaim himself to be "the best heavy in the kingdom." We'll drink cheap beer (but call it mead) late into the night and talk about the time he was promoted to dungeonmaster in a MUD.
