Drop a sweet loaf onto your partner's back or chest. The bigger the better, but it's gotta be clean and in one piece. If you want, you can use a toothpick to make it look like a steamboat, and then you can attach a flag to the toothpick and fly it on loaf. For some reason, I like the hammer and sickel, but you can put whatever you want on it.
Then, sit on your partner's face and urinate towards the steamboat. This will mimic the action of an Ol' Mississippi Steamboat.
ENJOY!
