The fox and the wolf meet in the forest. The fox says:
Hey! Let's beat up the rabbit.
Okay, but why? - asks the wolf.
If he's wearing a hat, then for that reason, and if he's not wearing one, then for that reason! - replies the fox.
They go to the rabbit and beat him up mercilessly. The next day, the fox starts again:
Hey! Let's beat up the rabbit.
But we already beat him up yesterday! - responds the wolf.
But today, let's beat him up again! - insists the fox.
Alright, but why should we do it today? - asks the wolf.
We'll go to him and ask for a cigarette. If he gives us one with a filter, then for that reason, and if he doesn't, then for that reason.
They approach the rabbit: - Hey, rabbit, give us a cigarette!
Do you order a filtered or non-filtered one? - asks the rabbit.
To which the fox exclaims:
Look at that, for heaven's sake! Once again, he's not wearing a hat.
