Joke's On You

New resource at NCTM's Illuminations, an activity that parallels proof structure with the structure of jokes.

But the main reason for this post is to spread the news of their 2010 Illuminations institute.  A group of teachers will come together to write new and interesting lessons.  Only open to K-12 teachers, so I'm out.  But you could be in!  Find out more.  There's a stipend...

From the always entertaining sometimes profane xkcd.

"Well, the telling of jokes is an art of its own, and it always rises from some emotional threat. The best jokes are dangerous, and dangerous because they are in some way truthful."  - Kurt Vonnegut

"The love of truth lies at the root of much humor." - Robertson Davies

Joke

From my brother:
A mathematician was confronted by his wife upon returning home at 3am.
'You said you'd be home at 11:45,' stated the wife.
'I said I would return at a quarter of twelve,' said the husband.

The funniest thing is that I'm always having these kind of conversations. Not from staying out too late, but from being too literal.
