A very simple site that generates two unlikely people that team up and fight crime! Here's some examples:

"He's a lounge-singing sweet-toothed gangster living undercover at Ringling Bros. Circus. She's an enchanted snooty museum curator with a flame-thrower. They fight crime!"

"He's an immortal misogynist assassin She's a mistrustful thirtysomething mermaid who believes she is the reincarnation of an ancient Egyptian queen. They fight crime!"
