Most nights after Katie finally crawls into bed, she asks me to fill her water bottle. When I return with the full bottle, Katie is invisible under the covers.
"Where's Katie?" I ask. "What am I supposed to do with this water bottle?"
A low growl comes from underneath the covers.
"Oh, my! A monster has eaten Katie! Come, monster, spit Katie up."
Massive tickling of the monster ensues with adlibbed dialog until I finally pull the covers back and reveal Katie's head, now that she has been spit up by the monster in her bed.
