What is good? Fruit salad. What is awesome? Rockin Fruit Salad inside a Watermelon. This is a simple trick that my friend showed me (and, I have on good authority, most of the world already knows) to make fruit salad much more awesome.
Step 2) Chop off top third of watermelon with a big ol' knife. Do this in a serrated pattern (just stab it and alternate the angle of the blade), and be sure to keep the top.
Step 4) Label appropriately. It is very embarrassing to bring the wrong rockin' watermelon to a gathering. I used a small knife and made very shallow 'v' shaped cuts into the melon to make the letters.
