Get the Running Backmug. 
This is a prank only pulled off by the professionals including my friend Darren. If you are getting a ride from anyone that you dont like or dont know, for example a taxi, then you calmy pull down your pants and take a shit in the back seat. As the smell reaches the driver's nose he will mostly likely turn around thinking what the fuck is that smell?? Then you yell o fuck watch out! This is best done at nighttime because the driver would probably slam the brakes. When the car stops you get out and run.
"Man Darren, that was smooth performing a shit and run in the back of Matt's car without using any T.P."
"Give that taxi driver a shit and run so you dont have to pay for the fare"
