Wu-Tang Clan members RZA, Ghostface Killah and GZA have partnered with White Castle to promote the US fast food chain's new vegan burger, The Impossible Slider.

The ad features RZA 'uploading his consciousness' to a machine, announcing plans to travel through space with the rest of the east coast rap group to 'seek wisdom, and expand the parameters of the mind', and urges viewers to call 1-833-4-SLIDER if they have questions about 'life, love or consciousness'.
