During Tony Yayo's incarceration, G-Unit began a campaign called "Free Yayo", which involved wearing "Free Yayo" shirts advertising his situation; due to the mainstream prominence of the group, Tony Yayo began to receive increased attention from the Hip Hop community, becoming known as the "mythical 4th member of G-Unit", although Yayo himself was unaware of the coverage he attracted. The campaign received widespread publicity, even in countries such as Brazil and Iraq. At the 46th Grammy Awards, 50 Cent and Eminem performed whilst wearing "Free Yayo" shirts. Yayo watched the performance on television in prison after receiving a call from the Shady offices advising him to do so; he had never seen the shirts before, and was inspired by them to work hard to improve his rapping before his release from prison. He was granted parole from his sentence on January 8, 2004, but was discovered to be in possession of a forged passport, following a check from his parole officer, and was sent back to prison until May 25, 2004.
