I do think sometimes there's danger in guest appearance mania. I've seen too many examples that sound cool on paper like 'Oh get that guy to sing the hook on that guy's song ' and then that's all it is. It's a cool idea that sounds good on paper.

Sometimes airport security people recognize me. I'll go through the whole screening process and at the end they'll go 'Hey man I really like your work.' That's so cool.

Sometimes guys are so concerned with being cool and hanging out with their friends. They don't want to seem like the guy that 'has to call his girlfriend.' It's just boys growing up.

'Ludacris' is something that I made up. It just kind of describes me. Sometimes I have like a split personality. Sometimes I'm cool calm and collected and other times I'm beyond crazy.

My strangest media moment a photo session they all had dressed up like 50 gangsters. That was pretty cool. We have to get some more of those kind of photos sometimes.

I get recognised sometimes and that's really cool. I've tried certain disguises but that doesn't work.

Playing and singing at the same time is pretty cool but sometimes it's difficult to know when you can just really let go a bit because you've got to get back to bloody microphone and sing some stuff.

Part of Obama's persona is self-reliance. He's calm he's cool he's self-possessed. In many ways he has tried to define himself in opposition to Clinton's sometimes needy often undisciplined emotionalism.

I think sometimes I guess you see records say you want to get there and use that as motivation. In a way it's kind of cool if there is a possibility to rewrite history and be up there with the greats of Olympic history.

Sometimes just when I say hello the right way I'm like 'Whoa I'm so cool.'
