This Halloween, Wednesday, October 31, Chipotle will treat customers dressed in costume to a burrito, bowl, salad, or order of tacos for only $2 between the hours of 4 p.m. and closing. Proceeds from the fundraiser, up to $1 million, will benefit the Chipotle Cultivate Foundation.

This year Chipotle has teamed up with Rob Riggle, a comedian who’s known for his work on Comedy Central’s The Daily Show, and the movie The Hangover. Together Rob and the Chipotle team are releasing a video to tout the event, which will of course support a good cause – guests who come in costume can score a $2 burrito and all proceeds from 4 to 11 pm will benefit Chipotle’s Cultivate Foundation, up to a million dollars.

Click here to watch the hilarious video of Rob engaging in Halloween hijinks – stealing candy, TP-ing the neighbors’ houses, and wrecking a police car – before arriving at Chipotle to redeem himself by purchasing his $2 burrito.

To participate in the fundraiser, go to any Chipotle restaurant in the US, UK, and Canada between 4 p.m. and closing on October 31 dressed in costume and purchase any Chipotle menu item for only $2. Participants in this year’s fundraiser are invited to also enter the Chipotle Costume Contest for a chance to win $2,500 and other prizes.
