Forty Percent Leadbelly

"Forty Percent Leadbelly" is the one hundred and twenty-eighth episode of Futurama, the fourteenth of the seventh production season and the fourth of the tenth broadcast season. It aired on 3 July 2013 on Comedy Central.

Story
Bender meets his hero, a famous folksinger who has been in jail 30 times, and wants to duplicate his success. This means duplicating his guitar too, which he tries to steal from a maximum-security prison, but fails, so instead resorts to 3D-printing technology to duplicate the guitar — again resulting in horrible consequences.
