A Bittersweet Victory

Alright, listen up, buttercup. This "joke" is about a guy who bets his pal will drown. He wins the bet 'cause, well, his friend kicks the bucket. But here's the kicker: it's "bittersweet" 'cause while he's five bucks richer, he's also pal-less. It's dark humor, get it? You probably don't because you think 'winning' is an Olympic sport.
