SF is one of the funniest members here (his humor
is underappreciated).
Not on his own. In fact, most of his threads bomb, probably due to his inappropriate use of ellipses in the titles and self-pitying autobiographical content.
But he's a riot when he has a foil. It could be you, me, Royalty, or just about anyone, really. He embodies the quote in Good Will Hunting by Robin Williams's character that some people don't believe in themselves until someone believes in them first. In short, he needs a trigger. But when he's triggered, he's funny.
