Hey Noah, whatcha doin'?"

Noah was in his back yard building the Ark when his neighbor comes along and says,"Hey Noah, whatcha doin'?"
Noah says "Sorry, I can't tell you".
His neighbor says "Awwww, c'mon" Noah".
"No, I can't" Neighbor, replied Noah. "
"Why not, Noah?"
"Because I can't"
"C'mon, just give me a little hint"
Noah *sighs* "Okay.......... How long can you tread water..........."
