The original ones from about 5 years ago were the best. The Sasquatch and the trailer, the hitchhiker with the head and the bag (and subsequent beating), etc. Now they tend to repeat themselves, so I can see where they are going. Though a caught a recent one with a flaming faery boy who was scared of some ghost-make-uped kid. He was so over-the-top I almost pissed myself.
Overall, it's a nice diversion or background noise. Although the people seem real, I am constantly amazed at how dim they are. "You will have to protect this super top secret zombie guy. All by yourself. With no phone or weapons. Have fun!" I could insert a bunch of cursing here describing that level of mental ineptitude, but you get the point.
