Former Two and a Half Men star Charlie Sheen accompanied police officers and several hundred people to raise money for bipolar disorder sufferers.
The actor marched through Toronto, Canada, on Friday, Dailystar.co.uk reports.
He asked followers to donate money before joining the charity fundraiser, telling the crowd: "I was called bipolar. You guys, I'm bi-winning right? I'm not sure what the f**k bipolar even means. It's a psychiatric opinion, which means that to me it's rooted in judgment."
Sheen pledged the profits to a Canadian bipolar group whose executive director said he was surprised and honoured by the actor's gesture.
