The real brain-bender is: "The following statement is true. The previous statement is false."


Consider the set of all sets which do not contain themselves. Does it contain itself?

How many logical statements could a logician chuck if a logician could chuck logic?

Han Solo: Kid, I've flown from one side of this galaxy to the other, and I've seen a lot of strange stuff, but I've never seen *anything* to make me believe that there's one all-powerful Force controlling everything.

I don't know for sure, but Chuck Norris could chuck it for certain...
