What's Not to Like?

I've got a joke for ya.
Would you like to hear a joke?
Alright.
Okay.
Ahem.
Sometimes when I'm warming up my throat before a really good joke, instead of saying "ahem," i like to say, "meha!"
Anyway.
Why did the lobster fuck his buddy's girlfriend?
Because he was a shellfish asshole.
Ta da!

Having sex with the best friend's girlfriend is really everyone's true romantic aspiration.
She often likes all of the same things you like.
Because she likes all of the same things that your buddy likes.
Which are all of the same things that you like.
Which is why you like your buddy and is why your buddy likes his girlfriend.
It only stands to reason that in time you start to like what your buddy likes.
In a woman.
And the nutty thing is that once you two start going for ice cream.
Without bothering to tell your buddy about it.
You realize that you like more of the same stuff than your buddy.
"Rainbow! That's my favourite flavour too!"
"Really?!"
"Yeah! I never get it with Buddy because he says-"
"-That it's too effeminate to be an ice cream flavour!?"
"Yeah!"
When you're finishing one another's sentences, handjobs are soon to follow.
And all of a sudden, you like the one thing that your buddy likes that you're not supposed to like:
Having sex with your buddy's girlfriend.
In time he finds out that you like the one thing that he likes that you're not supposed to like.
And he doesn't like it.
And now, what's more, he doesn't like you.
He doesn't like her.
And you wish that you'd never bothered noticing the things that she liked that you like.
Now all three of you dislike the scenario.
Yup.
Sex with the best friend's girlfriend.
Nothing quite like it.
