What are some of the worst spam emails or scam calls have you had to deal with?

Nearly every day for the past few months I get emails about viagra from some obviously fake pharmacy websites, some even claiming to be "Canada's best online pharmacy". A: I've never bought or touched viagra, B: I would never by drugs or medcine online, escpecially from such dodgy and made up sites, and C: I don't live anywhere near Canada.

And a while back I'd get 'courtesy calls' every Thursday from some made up business like Niagra Healthcare. I don't really know what they were expecting to get out of me if I'm 100% sure I've never bought or heard of their company.

So what spam or scams have you had to deal with? Do you know anyone who's been scammed in the past?
