Let's hope, and cross our fingers, that by milk they are referring to the addition of lactose, an unfermentable sugar used in so called 'milk stouts' to add a slight sweetness and richer mouthfeel, and by chocolate they are referring to a type of dark roasted malt that has slight chocolatey notes by virtue of the manner of roasting, and not, god forbid, and FSM preserve us, that they actually added chocolate milk to the stuff or made it as sweet as chocolate milk, since porter is already sweet to begin with.

The take-away:

1. Just because you can doesn't mean you should.
2. Don't spend so much time in the sun, even though you live in Florida. (See 1. above)
