Joannie Cunningham’s boyfriend in the wildly popular spin-off series from Happy Days. Fans were so upset at the cancellation of the series after just 2 seasons, it has become a ritual in the US to hand out small statues that look like a cross between Scott Baio and a pen at every single trade show you might attend.

I usually spell it “swag”, but pronounce it like “Schwag”.
