Turns out that some food scientists over at Texas A & M figured out that a chemical in the rind of watermelon helps relax blood vessels in the body. Supposedly, citrulline is the secret ingredient found in the white part of the rind that gives you that “little extra lift.”

So if you don’t want to spend the money on that little blue pill; cut off a few pieces of the big green rind and eat that. Be sure to call your doctor if you experience an erection lasting longer than four hours.

Then again if you don’t have a lot of trouble in that department you can always cut a hole in that sexy thing and make your contribution to science like this guy.
