How does your garden grow?

The husband and Elder Son were working in the garden over the weekend. The husband in charge of plants and tools, Elder Son in charge of filling and emptying the watering can.
At one point, I observed Elder Son swinging the can in a manner that caused the water to fly across the garden (perhaps on purpose but I can't prove it) and splash the back of his father's follicly-challenged head.

I called over, "Elder Son! You can water him all you like, but your father isn't going to grow any taller!"
He replied, "I was just trying to grow him some hair!"

Yeah.
Nice knowing you, son.
