I'm looking for a story where Michael goes into a convenience store for a bag of chips and a soda, but forgets his wallet at home, so he signs over part of a Beatles' song to the store clerk on the back of a brown paper bag as payment:
To Whom It May Concern,
I, Michael Jackson, King of Pop, do hereby assign twenty percent (20%) ownership in the future publishing rights to The Beatles' song titled "Good Morning Good Morning" to Lxxxxx Pxxxxxxxxx on this date, 7/23/2004, in exchange for one 6.3-ounce bag of Cool Ranch flavor Doritos and one 20-ounce bottle of Diet Mountain Dew Code Red soda.
Michael Jackson (MJ)
Harvey Sxxxxx, a customer
But don't try to copy this one; I've just submitted it myself through my attorneys.
