We sing a Watermelon song with my Girl Guide pack. It's an action song:

Just plant a watermelon right on my grave Let the juice (schlurp)slip through Just plant a watermelon right on my grave That's all I ask of you

Well southern fried chicken might taste mighty fine But nothing tastes sweeter than a watermelon rind...pizza!

So plant a watermelon right on my grave Let the juice slip through-oo-oo

(It sounds a little familiar to the one Night Owl talks about above...a children's action song with sound effects.)
