When B.O.B decided that he wanted to be a rapper . . . his father was NOT happy about it.  He says, quote, "My dad was a preacher.  When your dad is a preacher . . . the things you wanna say as an MC, they don't really go hand in hand.

"I remember I was walking through the house with a rap book, a do-rag on and some headphones or something, and my dad stopped me.  He was like, 'Why are you trying to be something that you're not?'"

B.o.B. adds, quote, "I was appalled.  I was like, 'What do you mean, something I'm not?'  I'm an MC, I'm a lyricist, I'm a rapper . . . I love this."  (--You can find video of these comments on MTV.com.)
