Slap and Counterslap?

The only thing stranger than slapping our hands together to praise someone is the fact that we flush and feel honored when enough people do it for us. How did the collision of meaty appendages become a symbol of honoring? Does it have something to do with the fact that God cursed the dragon by relieving him of the right to limbs? Are we exulting over the seed of the serpent every time we clap?

Wow. That was random.
