I remember seeing a "bump" (kind of, but not really) that would only show after a few specific shows (I forget which shows, sorry :\ ) and it would play a video of the Tacoma Narrows Bridge (video here: http://www.youtube.com/watch?v=1RI9M2G0VSA (http://www.youtube.com/watch?v=1RI9M2G0VSA)
The audio that accompanied it would be 2 high-ish pitched bell gongs, then a guy yelling and it would cut out. If anyone can find it, I'd be very grateful.
Wow, I have only the vaguest recollection of that :| I don't think it was a bump, though, it looks more like a piece of random that they tack onto promos.
I'll see if I can't find something on it...
