There's a video of him addressing the conspiracy theory, obviously denying it.
I seem to recall it being about a different guy, but all I can find is this Rob Ford guy. He wound up being the mayor of Toronto and had many scandals or run-ins with the media, big hoopla stunts for local television.
Rob Ford is now dead since 2016, allegedly. In other words, Chris Farley retired a second time. Who knows what he's doing now.
