New Rick James doc reveals how penis-wielding coke binge helped Lionel Richie

He’s Rick James, bitch — and don’t you ever forget it.

That classic Dave Chappelle catchphrase is exactly the kind of emphatic statement that the late “Super Freak” funkster made in one encounter revealed by his former manager Kerry Gordy in the new documentary “Bitchin: The Sound and Fury of Rick James,” which premiered Tuesday night at the TriBeCa Film Festival and will be available to stream on TriBeCa at Home beginning at 6 p.m. Wednesday. Gordy — eldest son of legendary Motown Records founder Berry Gordy — vividly describes how James, frustrated by disappointing sales for his 1982 album “Throwin’ Down” and its accompanying tour, marched into the office of then Motown President Jay Lasker to deliver his next LP. Then he proceeded to pour coke onto Lasker’s desk, snort it, jump on top of said desk, take out his penis — and shove it in Lasker’s face while yelling “Sell my goddamn record!”
