Four friends are gathered at a pub. They have in front of them two 8-pint trankards full of beer, and an empty 3-pint mug.
Since they are still sober, they quickly calculate that they have 16 pints for the four of them, which comes out to an even 4 pints per person.
Can they divide the beer equally with the containers they have available?

Except that there's only one 3-pint mug, and I don't think you can just "pour half" of something out of the tankards. By the way, who makes a one-gallon tankard??
