New glasses?

I got new glasses last week. And now the following exchange is stuck in my head:

Marge: Have you noticed any change in Bart?
Homer: New glasses?
Marge: No...he looks like something might be disturbing him.
Homer: Probably misses his old glasses.
Marge: I guess we could get more involved in Bart's activities but then
      I'd be afraid of smothering him.
Homer: Yeah, and then we'd get the chair.
Marge: That's not what I meant.
Homer: It was, Marge, admit it.
