Jokes about "I think, therefore I am" are always amusing to students of logic, because people twist themselves in knots trying to make it seem weird, when the only thing you can do with "I think -> I am" is "I am not -> I think not", and "Rene Descartes died, therefore he stopped thinking" isn't funny.
I'm sure someone will point out if I am incorrect here, but:
Isn't it somewhat irrational to analyze why a joke isn't funny? Isn't it sortof like trying to use a rational analysis to demonstrate that you should or should not like the sound of birds?
I mean, hey now, c'mon.
( In any case, the joke wasn't "Descarte died thus stopped thinking". )
