So there were three friends: Happy, Sad and Sorry

Happy was a beautiful young girl, and Sad and Sorry were two close friends of hers.

They used to hang out and have fun together, but the two kids always had a crush on her, but kept quiet about it.

Sad had always been the most beautiful one, while Sorry was a really nice but average guy.

Anyway, years went by, and eventually Happy and Sad ended up together, but they were still young, so their love was expressed in hugs and kisses, and nothing more.

Sorry, however, felt really bad about it, and so he decided to go to the gym and work on himself.

Another year went by, and lo and behold, Sorry became a beautiful guy, and for the first time Happy felt attracted by him.

Sad became jealous and decided to take his relationship to the next level. "Happy", he said, "tonight I want to make love with you".

She was still a virgin, and blushed a bit after being asked such a question, but eventually her face showed a beautiful smile. "I'll see you tonight" she said, and they both went home.

That night Sad kissed Happy, and hugged her, and slowly removed her clothes. He started with her t-shirt, and felt the soft skin of her belly under his hands. He removed her bra and rested his head on her chest, feeling her heartbeat accelerating.
He then removed her pants and worked his way down there.

Then he stopped.

"Honey, what's wrong?" said Happy.

He suddenly threw a punch at her, then grabbed her by the shoulders, and staring at her yelled:
"ARE YOU FUCKING SORRY?"
