Riddle Me This:

How is it possible that Ike can go to bed (at 5:00, God help me!) and sleep through Simon running and playing and complaining about going to bed... but he manages to wake up at the sound of me slipping between the blankets in my bed?

It's uncanny. Much like the X-Men, but less cool, and with a disappointing lack of Hugh Jackman and/or James Marsden.
