At the end of a long crime fighting day, Superman decides he needs to relax for a few hours, so he rings spiderman to see if he'd like to go out for a drink.

 

Spiderman replies "No, I have to repair my web spinner."

 

So, Superman rings a few more of his super hero friends and they're all busy. He decides in the end to go for a quick super-fly around the world to clear his mind before bed time. 

 

As he passes over Wonder-Woman's mansion he sees her lying naked and spread eagle next to her pool. 

 

Hmmm he thinks, with my super powers I'll fly down for a quickie and before she realizes I'll be gone. 

 

So he swoops down and "WHAM BAM thank you maam" and he's gone.

 

Wonder- Woman shreiks "What was that?" 

 

And the invisible man cries "I don't know, but I've sure got a sore ass!!!"
