HBO's "Winning Time" hit the nail on the head (literally) when addressing Spencer Haywood's infamous self-circumcision ... 'cause the Hall of Famer tells TMZ Sports everything is 100% true!!
In case you haven't tuned in to last week's episode of the hit series about the Showtime Lakers, Haywood's teammates gossip about how he was known for, uh, taking matters into his own hands and putting a razor to his junk when he was a kid.
While some folks featured have criticized the validity of events on the show, we spoke with Haywood about Wood Harris' portrayal of his character .
