Uranium, Potassium, Fluorine, and Carbon all walk into a bar, late one Saturday evening.

Fluorine goes up to the bartender and orders a pint of scotch. Without question, the bartender fills up a glass and hands it to Fluorine.

Uranium then goes up to the bartender and orders a pints of gin. Again, without question, the bartender fill up a pint full of Uranium's gin that he ordered.

Carbon follows, this time ordering a pint of rum - his favorite! The bartender conforms, giving Carbon his pint, and carries on.

Potassium, however, orders *two* pints of his personal favorite vodka, claiming he had a rough day. The bartender understands, and he gives Potassium his fifth of vodka that was ordered.

The four elements chug their drinks in mere minutes! The bartender rushed over, thinking something had gone wrong, and... FUCK! I forgot the punchline!
