Toronto had Zanta, a guy who wore red boxers, black boots and a Santa hat and did pushups on top of mailboxes and flexing while shoutting at passersby. If you knew him it was a fun spectacle but for most people he was aggressive and basically a creep.
He was mentally ill for sure, and had a pretty long sad story.
Any Zanta experts please speak up if you'd like to add more context. Pretty sure someone wrote a book or comic about the guy.
