Watermelon always tastes so good in the heat, and it you spike it with some lime flavored vodka its even better. You make a hole in the watermelon all the way into the meat. Place a funnel in the hole and pour in the vodka. It takes a long time for the watermelon to soak it up. 2 cups takes about 2 days, so do it in the fridge.
The result is awesome. Cut the melon into wedges and serve.
