Yesterday evening, the four year old son of some friends had what I deemed to be a creative idea: He used a water fountain to splash the lower half of his face and then ran around yelling "Water Beard!" I didn't voice my admiration because it wasn't necessarily in the best interest of the otherwise dry carpet (and his fleeting "not currently in trouble" status).
"Water Beard" sounded to me like a pirate. Please understand that anything in a liquid state is more clearly conveyed with the use of color. You'll just have to pretend that the beard is in some lovely shade of blue or sea foam green.
