Comedian Demetri Martin's remarkable palindromic poem on alcoholism, written for a math class he took at Yale. 
http://en.wikipedia.org/wiki/Demetri_Martin
Demetri Martin's Palindrome. In the spring 1993 semester, Demetri Maritn prepared this palindromic poem as his project for my fractal geometry class. Notice the first two and last two lines are palindromes, the middle line, "Be still if I fill its ebb" minus its last letter is a palindrome, ...

Three statisticians go hunting. They spot a deer. The first statistician shoots; the shot passes a yard to the left of the deer. The second shoots; the shot passes a yard to the right of the deer. The third one yells, “we got it!”

A fun application of a discrete analog of the intermediate value theorem, thanks to futilitycloset.com:
A problem from the 2002 Moscow Mathematical Olympiad: A group of recruits stand in a line facing their corporal. They are, unfortunately, rather poorly trained: At the command “Left turn!”, some of them turn left, some turn right, and some turn to face away from the corporal. Is it always possible for the corporal to …

Easter joke:-)
John Deering's "Strange Brew" is just what the title says -- a mix of strange and humorous observations.

If this weren't true it would be funny. From slashdot.

+Alan Light You seem to be a MRA so I'm not going to bother discussing anything with you, except to say I don't live in America so none of the examples you've given of legislation mean anything to me. But anyway, bye.

Fascinating and clever post on sestinas:-)
The sestina is an unusual form of poetry: Each of its six stanzas uses the same six line-ending words, rotated according to a set pattern: This intriguingly insistent form has appealed to verse writers since the 12th century. “In a good sestina the poet has six words, six images, six ideas so urgently in his …

I have used All for the Pet for years and never once had rude service. The store doesn't even open until 9am and Lisa often comes in early to help out people who want to drop off their pet before going to work. I think she does a good job with my pets and her prices are reasonable.
