So Superman is flying around in SuperHero World. All is good except he's feeling a little randy. After flying around for a while he sees Batman up ahead.
"What's up Bats"
"What's up Supe"
"Oh, you know, it's all good except I'm horny as all hell"
"Well, you know there is Wonderwoman, she's a slut, you should go find her."
"I can't Bats, she's a really good friend, couldn't do it"
"Well, thats your loss Supe"
Superman keeps flying around, soon he see's Spiderman hangin' on a rooftop.
"Hey Spidey"
"What's up Supe!"
"Not much, I could really do with a shag though."
"I saw Wonderwoman earlier, she'll f*k anything, we've all done it."
"Nah, I can't, it wouldn't be cool at all."
"Supe, man, you're missing out."
Superman goes on his way. Soon he's flying over a field and he see's Wonderwoman lying there completely naked, legs spread.
This is too much of a temptation for him, and he thinks about it for a minute.
"I am Superman of course. I'm faster then a speeding bullet. I could be in and out of there before she even knew anything had happened."
He decides to do it.
Suddenly there is a flash of light and a sonic boom.
Wonderwoman says "What the hell was that?"
The Invisible Man rolls off her "I dunno, but my arse is killing me!!"
If I were any funnier I'd be twins.
