5'6"

How the Scene played out:

Dan: How tall do you think James Brown was?
Dave: Five-Eight or so
Dan: Are you really as dumb as you speak, that man was only like Five Four.
Dave: You are calling me dumb, at least I am not dumb enough to spend my nights in bed with that skanky cow Stacy, and the man was tall man
Dan: First of all Stacy has not lost all of her pregnancy weight yet, she will get there and you know that we are struggling with that, so play nice, and the guy was short.
Dave: I am telling you he was five seven, five eight, and dude you should be happy that any girl would stay with you, with your outdated Hawaiian shirts and your Converse All Stars and fro-ey hair you look like a 400 pound Screech.
Dan: Okay just stop it right now and agree that he is short.
Dave: Or what? are you gonna waddle to Mr. Belding.
Dan: Or How about this
Dan takes out a gun
Dave: Whoa whoa whoa. Look the guy's tall but there is need to get upset about it.
Dan: I've heard enough
