Since this turned into the "random places you've ran into famous people" thread:
I went to the grocery store this afternoon. I'm walking down the right side of the aisle and on the left side are two people with carts in the row, coming towards me. The 2nd guy is wearing a hooded sweatshirt and a non-descript baseball hat. I notice he looks vaguely familiar, but I can't place him. As I approach, he moves he cart to pass the first person, but stops to grab something and blocks me. I look at him and wait trying to figure out who he is. He looks up, pulls the cart back out of my way, and says "Hey buddy, sorry about that." I give him a quick "no problem" and take two steps before I realize who it is, Garth Brooks.
