Lois: Boys will be home in ten minutes.
Hal: I'm willing to accept that challenge.
Lois: No, Hal. I just went to the doctor. I have a low-grade infection. I have to take antibiotics. And we can't have sex for a week.
Hal: What?
Lois: Not until I finish these.
Hal: Okay, okay, let's try to look at this rationally. What would happen if you took them all at once?
Lois: No, Hal.
Hal: Or- Or what if we alternated?One day off, one day on. I'm not a medical doctor, but I think it would be a lot less of a shock to your system.
Lois: A week, Hal. No sex for a week.
Hal: Wow! [whimpering] All right, I'm fine. I'll just uh... I'll go mow the lawn. Do we still have that mower?
Lois: Hal?
Hal: Huh?
Lois: Clothes.
Hal: Oh, right.
