Rappers. When they're not busy wearing grills, popping tags and forgetting where their 'b**ches' are at (for the record, they're almost always in the bedroom), it appears that they spend a lot of their spare time worrying that you won't actually remember their names.
So much so that even when you've spent all your pocket money downloading their latest album, they feel the need to politely keep reintroducing themselves. And we're not complaining. Here are some of those lyrical gentlemen doing just that. (Remarkably this is safe for work.)
