take 1 seeded watermelon and cut that baby in half or buy one already halved. and stick those birthday candles in it. then light them. then blow them out. after that you can light them and blow them out all night long. eventually cut it then serve it. all to you and maybe some guests.
i say seeded because seedless is just not right. even if you dont eat them they should be there. if you eat seedless you become seedless. so for all you men out there. put some lead in your pencil and eat your seeds.
