Marilyn Manson -- Antichrist Superstar Returns to Roller Skating

So what did Marilyn Manson do this weekend ... drink the blood of a unicorn? Double date with a couple witches and a warlock? Nope, he just went roller skating in Oklahoma ... naturally.

The goth rocker showed up at Skateland in Tulsa on Friday night. Manson is in town filming a movie where he plays a hitman, and they were shooting at the rink. According to the manager, Manson's character wasn't in the scene, but he came along for the ride so he could get his skate on.

The manager says Manson rented a pair of skates, and revealed he used to speed skate when he was a kid. All told he roll bounced for about 2 hours and didn't fall once. Not bad for his first time in 20 years.

Manson's still got a thing for the wheel life, obviously -- he played a skate rink employee on a 2013 episode of "Eastbound & Down."
