...particularly when the guys at Jalopnik are able to crash the Indy 500 parade, and somehow end up in the damn thing. They were in the car that was just ahead of the Row 1, in fact. Here, I'll let them explain (part 1, and part 2). The amount of fun these guys seem to be having is just not fair.
And now, the important part: They may have gotten their "You're With Me, Leather" sign on TV. They believe that a camera was pointed at them, with the little red light on in the midst of the parade's "TV Zone." If someone could confirm this, the entire would would be eternally grateful.
Here's video of Ray at the parade, being very parade-y, and a little bit insane.
