If he really is 5'2, then he is shorter than Brooke Shields, the object of his "spirited" defense. Not to mention the designer himself would have to be of similiar stature in order for the headbutt to have actually landed, otherwise it probably would have been an openshirtgoldnecklacebutt (the Ben Stiller basketball scene in Along Came Polly comes to mind The Link)
It also raises the question of where was Keifer when Brooke needed defense from Tom Cruise? That would look to be a fair fight, if not illegal midget wrestling. Gotta go with 24 over Mission Impossible there. Keifer did ride rodeo while Tom was learning to trampoline.
Lastly, for the historical record, Naplolean was 5'6 1/2 which was above-average height for cheese eating surrender monkeys of that period.
