When you're watching TV while a plumber is installing a new toilet in the master bathroom above your head... and he shut off the water main over an hour ago.
When Noah has shut and locked the doors of his family owned homemade luxury liner and you find yourself relegated to the outside of the ark while a muzak version of "Raindrops Keep Falling On My Head" ominously and ironically plays.
At least you wouldn't have to move the sprinkler all summer long and might save on your water bill?! If it collapsed, think of it this way: It would be easier to move to my house if it gushed water all over your backyard already! ;) ;)
