Superman
One sunny afternoon Superman was out flying around.
Crime was slow that day so he decided to go over to Spiderman's house. "Hey Spiderman", said Superman, "lets go get a burger and a beer!". "No can do" said Spiderman, "I've got a problem with my web-shooter. Can't fight crime tomorrow without it".
So Superman went over to the Batcave. "Hey Batman", said Superman. "Let's go get a burger and a beer!". "Not today Supe", said Batman. "My Batmobile has a flat tyre and I've got to fit it today. Can't fight crime tomorrow without it".
A somewhat disgruntled Superman took to the air, cruised around the skies and found himself over a penthouse apartment. And what did his super vision see? None other than Wonder Woman lying on the deck spread-eagled, stark-naked.
Superman had a brilliant idea. "They've always said I'm faster than a speeding bullet and I've always wondered what she'd be like!" He zoomed down, did the deed and flew off in a flash.
All of a sudden, Wonder Woman sat up and said, "What the hell was that?" And the Invisible Man climbed off her replying, "I don't know but it hurt like hell!".
