Mark Malkoff's Free Cab Rides

Comedian Mark Malkoff offered New Yorkers free cab rides for an entire day. He hired a cab driver and kept the meter running for fourteen hours straight! New Yorkers could either Tweet or Facebook message him for rides which resulted in hundreds of requests.
Along the way they did fun stuff that's never been done in a cab before including filling the entire cab with popcorn and plastering Tony Danza's face all over the cab. The grand total on the 14 hour cab ride turned out to be $486.10.
