It's a pool

Last night, I took the kids for a night swim at our neighborhood pool.  A man came up to me and pointing to Eli who was sitting on the steps of the pool, said "Is that your son?"  I said, "Yes, and oh my gosh, what has he done, or what did he say?"  He said he went up to Eli and said, "Hey buddy, how's the water feel?"  Eli replied, "Dis is not a water feel, it's a pool."
