The handshake: Extend hand with the fingers all loose, curled and noodley.
Today at the grocery store I passed some colanders on the shelf. I was tempted to buy one and wear it on my head while I shopped.
When you see someone walking around in a yarmulke, hijab, cross necklace, CTR ring or other religious paraphernalia, wouldn't it be comical to be wearing a strainer on your head and nod at them in understanding? OK, I'm joking but they all might as well be wearing strainers.
