The pair have teamed up with SIM only providerGiffGaff for it’s Unlock A Phone, Unlock A Chicken campaign.
Under the title K-Orville, Keith and Orville perform the rap CONtract in the Eminem-esque style video.
A giffgaff spokesman said: “giffgaff wants to be a force for positive change. We don't lock people into long contracts and we don't think battery hens should be locked up but instead re-homed. This campaign will not only liberate people tied to long mobile contracts but also raise awareness of battery chicken re-homing programs and who better to do that than the world's most iconic bird...oh and Keith."
Albion, the design agency behind the video, told Marketwire: "People on long mobile contracts are analogous to battery hens, laying profit for big mobile companies.
“We launched the idea of unlocking real battery hens through new SIM activations last year, and the giffgaff community loved it. We're now giving them shareable content to help get the chicken love out there. And yes we know - Orville is a duck."
