Lil Wayne Reveals How He Spent His Time in Prison

In his first post-jail interview, Lil Wayne opened up about his eight-month stay at Rikers Island, discussing how he spent his time and his job as a suicide prevention aide. Apparently Weezy spent much time listening to the radio (Hot 97, oldies) and reading biographies of musicians including Jimi Hendrix, Anthony Kiedis and Marvin Gaye, as well as the Bible. But one of his favorite ways to pass the time was playing Uno with his cellmates, which he was quite good at. "I'd bust a nigga's ass at Uno," he said. "We gamble for phone time. I'd take nigga's commissary: Lemme get them cookies, lemme get them chips, get that soup." Who knows, Weezy could go family-friendly for an Uno endorsement deal. ( Rolling Stone)
