A Fox Squirrel.
A Fox Squirrel. - 

This final note today, in which we learn technology is the least of our problems when it comes to market glitches.

There are fat finger trades, there are flash crashes and ... there are squirrels.

They've take the Nasdaq offline twice in the past 25 years. Once in 1994 by chewing through a cable, and once in 1987 by short-circuiting some power lines.

The squirrel in that one, sadly, didn't make it out alive.
