"Money Back Guarantee" is a 2006 song by underground rapper Pigeon John, from his album And the Summertime Pool Party. It features heavy sampling of the Pixies song "Hey", from their 1989 album Doolittle. The song chronicles the rapper's attempts to pick-up a woman despite the fact that he's not "pimp or athlete or hip-hop star." He promises that if she doesn't like the date she will "get [her] money back for free."
The song was featured on NPR's All Songs Considered.
