;) the easy one:

X=0.9999...

=> 10X-9=X

=> 10X-X=9

=> 9X=9

=> X=1

I already told this joke to Reza, but adding to the blog for posterity...

"A mathematician was trying to explain the concept of limits to an engineer. His analogy was this:

Suppose you have a beautiful naked woman tied to a post, and every time you take a step toward her you can traverse only 1/2 the distance between you and the naked lady. Will you ever reach her?

The engineer replied (with a good ol boy Texan accent; he was an A&M grad I think :) )

"I don't care, as long as I get close enough to do some real good""

ice story!
