One time on RAW, HBK was heading toward the ring. He got down on his knees on the ramp (and I think laid down). His clothes got stuck on the ramp, so he had to take off his accessories and got up and said something to the effect of "That shouldn't happen to me". I thought it was absolutely hilarious and wanted to see it again but I can't find it anywhere.
I was trying to find clips of the angle WWF did where they brought Brutus Beefcake back under a mask. He would run in during heel matches and save the babyface (I specifically remember Earthquake). I've heard the gimmick refered to as the Mariner and Furface.
As for the Shawn Michaels thing, I always wondered why they ran a mat out during his entrance during the live shows I attended. Now I know, always thought perhaps his knees were getting too tender.
The woman in charge of putting it down/picking it up is amazingly quick too*. It appears during a close-up right before he kneels and is gone by the time they get a shot from the ramp when he's going toward the ring.
*I watch for her when I'm there live, and always wanted to give her some appreciation for a job well done that seems like a nightmare.

Starbucks give away the grounds as mulch. You can go in and there's usually a fake tree with silver bags around the base in a pot, with all the free grounds you can take. As seen here: http://www.starbucks.com/aboutus/compost.asp
