Grog is a magical potion that is commonly served in bars and pubs that bestows upon the drinker awesome powers.
Possible awesome powers include;
Becoming the most knowledgable and funny man alive.
Inability to feel pain.
Inability to stand up.
Desire to mate with the nearest member of the opposite species, regardless of their level of attractiveness, availability, or how dead they are.
I love grog.
