“Farted on my wallet and now I have gas money”

“Gas money” means “money to buy gas (for the car),” but there’s a joke:
 
“Farted on my wallet and now I have gas money.”
 
“I farted in the room and charged everyone gas money” was posted on Twitter on November 3, 2010. “She farted on my wallet ...... we call it gas money” was posted on Twitter on January 5, 2011.
 
”#RapLikeLilWayne: Just farted on my wallet, call that gas money” was posted on Twitter on September 2, 2013, when it went viral. The rap is like Lil Wayne, but not actually from him.
 
The jocular saying has been printed on many images.
