Have you ever been to the Ludaverse? Well, you should visit it someday if you haven't, it's a wondrous place where Ludacris has arms like Donkey Kong and beats the shit out of buildings and mail boxes before hanging out with some little kids. But I think the moral of this story is something we can all take to heart. Always wash your hands after you piss, and never bother another man at the urinal, that's just rude and obtrusive.
Now, I understand that when you see Ludacris it doesn't matter where you are, you just want to talk to him. But you have to understand a man needs some alone time at the urinal and if you bother him he's gonna tell you to to get back and handle you a bit before he breaks your legs and cripples you against the wall, because he aint playin around, yall don't know him like that. And you just might get swung on. Check it out.
Also, if Ludacris is high when you meet him make sure you wear sensible shoes or he might just yell at them.
