Kungaloosh, IRL!

Have to add this one for a friend of mine.

You will need:

1 large watermelon. A spherical seedless won't do it. You need to be able to use the watermelon rind as a vessel for your finished product.
1 fifth vodka. Ok you can use less, but you'll want to cry when you run out. Midgrade is fine, don't use high dollar stuff here.
1 gallon orange juice.
ice

Now, seeing as how your MO here is to get drunk, there are a lot of ways to go about tackling this delicous but work intensive cocktail. First off, cut that watermelon in half lengthwise. Remember, it's going to be a bowl of sorts, so try to cut it in a way that it will hold liquid without wasting too much of it. With a large spoon hollow out the flesh of the watermelon. If you have a food processor, just throw the chunks in there, seeds and all, and finely puree it. The seeds will pretty much disappear. If you do not, you'll have to do some de-seeding before you mash this stuff up. We found that using a potato masher through a sieve into a large pot worked pretty well. Just make sure it's not so fine that it takes you a hundred years or so large that all the seeds get through. Depending on the size of the watermelon, this is going to end up being A LOT of watermelon puree. More than you can use in one batch, so put it aside in the fridge until you need to make more... and you will need to make more. ;)

I like to start out with a 2-2-1 ratio of watermelon juice, orange juice and vodka. I'm also kind of insane and love the taste of vodka, you will probably want to alter this depending on your tastes. The point is to make sure it all fits in the hollowed out watermelon half (if you haven't destroyed it in a drunken fit of silliness yet). Add some ice to keep it chilled, and when it's to your taste, well, get out your gravy ladle and spoon it on top of some ice and get crunk! Krunk? Whatever.

Make more using your reserves as you see fit, but be careful! The high water content of the watermelon makes this stuff sneak up on you, however, it also helps you avoid the hangover!
