It took almost 19 years, but someone finally figured out the actual date of Ice Cube's now-famous "Good Day." (Caution - this is post-NWA Ice Cube, not Are We There Yet? / Are We Done Yet? / Are We There Yet? (TV Series) Ice Cube, so: swears.)
Spoiler alert: it's January 20, 1992.
UPDATE: Ice Cube, through his publicist, will neither confirm nor deny.
UPDATE #2: Or is it November 30, 1988?
