Everything I know is wrong.

The Banach-Tarski Paradox is cool.

Of course, I don't really understand how it works, but it's nice to know that, in principle, one can disassemble a golf ball into a finite number of pieces and reassemble it into the planet Jupiter.

but you could only make a mathematical golf ball into a mathematical Jupiter

Now you've got a Weird Al song running through my head...

"Everything you know is wrong
Black is white, up is down, and short is long
And everything you thought was so important doesn't matter.
Everything you know is wrong
Just forget the words and sing along
All you need to understand is
Everything you know is wrong!"

...a guy behind me popped right out and cupped his hands across my eyes...

Woohoo!
