Superman is looking to have a night out. He calls Batman. Batman out with Robin. He calls the Invisible Man. He doesn't pick up his phone. So he's flying around the city looking for something to do. With his super sight he sees into Wonder Woman's window, and she's spread eagle on the bed. He thinks "I'm faster than a speeding bullet. I could fly in, do my thing, and then fly out and she'll never know." He does this and while he's flying away he hears Wonder Woman with his super hearing saying "did you hear something?" and the Invisible Man saying "No, but man my ass hurts"
