It's time for bed!... Or is it?

Duncan does not like going to sleep—and he'll do anything to avoid it. Until one day, his mom has had enough of his stalling and leaves him to figure it out on his own. "Try counting sheep," she suggests. Which actually turns out to be kind of fun. At first. But when it's Sheep #68's turn to jump over Duncan's bed, he won't. He needs a drink of water, he says. Then he has to go to the bathroom. Then he wants running shoes. Will Sheep #68 ever do what he's supposed to?
