This is what happens when you get an unusually hot and muggy day at the end of a Midwest summer, you have a large watermelon on your kitchen counter, mint in your garden, and an almost full bottle of vodka in the freezer:

Accidental Watermelon and Vodka Fruit cocktails!

Recipe

Chop enough watermelon to fill a Martini glass
add 1 shot of Vodka

grab the nearest spoon and dig in!
