Wear a bear suit. (Not like in an old Kanye West video, but the type of suit one might wear if one had to fight angry bears.)
This ... and I don't care which bear suit you wear ... watching an average-height-laffy-belly go ape-sh*t on a dude wear a bear mascot outfit would also create uncontrollable laughter ... tell him to at least rock the head to hide his gingerness.
