Not much too this, except it's surprising Danny hasn't had to do this before. Also, while it's in character for him to mix up the schedules, it really is something the girls should have spotted and suggested a change. Finally, would Michelle really be okay playing by herself for 4 hours? Then again, maybe she made a bit of a mess & she & Comet just cleaned it up, or maybe they find a bigger mess and maybe she even gets timeout for it after the episode's over. One of those times again we have to accept we don't see everything that happens in this family's lives.
