Today's topic - very unlikely hypothetical situations that you've heard a hundred times, but never really get old.
Case in point...
The boys in the class answer:
If you, your mother and your wife were all in a boat that sank, neither of them can swim, and you only have time to save one of them, which do you save? Why?
The girls in the class answer:
You are in a boat with your husband and mother-in-law. The boat sinks. Neither you, nor your mother-in-law knows how to swim, and there's only time for your husband to save one of you. Who should he save? Why?
