(Strip Number 1421, Original Publication Date, 16 February 1989)
Panel 1: As Mike turns on the television, Christopher asks him how much his parents are paying him to babysit. Mike says that he never asked.
Panel 2: Christopher says that he bets they're paying Mike five dollars an hour. Again, Mike doesn't really know.
Panel 3: Since this is the second time Christopher has brought this up, what Michael would like to know is why how much he's being paid is so important to him in the first place.
Panel 4: As Christopher turns the sofa into a trampoline, he cheerfully states that he an'Richard gotta make sure that he earns it. This alarms Micheal.
Summary: It's starting to look as if Lynn is using this arc as a means of avenging herself on either kids she sat for growing up OR her own kids. That's why Mike is scrambling around out of his depth and feeling as if he's being taken advantage of because that's Lynn as a parent.
