Pull!

Every night (well, every night that he's not on call, or at a church meeting, or late coming home, or whatever), John reads the girls two bedtime stories (Piggie Pie by Margie Palatini is a new favorite), and then he has this little tradition.
"Pull!!" he says. There is no way on earth this otherwise perfectly healthy 28-year-old man could possibly get off the bed to pray. He needs all the help these little (60 pounds combined weight) girls can give.
It requires their full strength, arms and legs, to get him up.
(Forgive the views of under my bed and the piles of laundry in the background. Embarrassing!)
