There are various stories that claim to tell the true history of Kanye West and Kid Cudi's initial meeting. This KTT thread covers the bases, but we know for sure their collaboration really began in Hawaii.
Cudi's then-manager Plain Pat had introduced Kanye to the music, and a fuse was lit—shortly thereafter, the Cleveland rapper was on a plane to take part in one of modern music's most legendary writing sessions.
Cudi was a major contributor to 808s and Heartbreak, and he signed to G.O.O.D. Music in 2008. Their work together since is nothing short of staggering—from "Gorgeous" on My Beautiful Dark Twisted Fantasy to "Father Stretch My Hands Pt. 1," these two have made history together.
In Kanye's words, "Me and Cudi created this shit."
