First of all, let me make something clear:
He was not making a joke AGAINST Irvin. He merely said that he was on his way to "Ricky William's" house. That's more of a shot against Ricky than anyone else.
Also, how can you compare Lavar Arrington not playing to this situation? Lavar Arrington not playing isn't funny, not like it's a serious matter, it's just not funny. As in, I don't laugh at it because it's not funny, not because I think it's serious.
Getting caught with a crack pipe is funny, no matter who you are...especially if you're someone like Irvin who sometimes acts like a crackhead on Countdown anyway. Lavar not playing ... for Christ's sake I don't even know how you compared those 2 situations. They're COMPLETELY DIFFERENT.
I'll answer your question so you can save some finger muscle though: Yes, I WOULD laugh if Corey Dillon was caught. Or Branch, or Brady, or Eugene Wilson, or Mark "Blunt" of the Celtics. Yankeessuck013 made a funny little joke. Stop s***ing your pants over it.
