Moe's been with a woman; he isn't gay, just ugly. I've never seen Barney even talk about women, except to give Homer advice, so maybe it's him, but then who would the writers have him marry? Smithers is already about as out of the closet as he can get on a cartoon (unless you count Robert Smigel's 'Ambigiously Gay Duo'). My money's on Lenny and Carl. They've been inseparable for years. But who knows? It's probably Nelson Muntz. Ha Ha!
