OS X Leopard’s “Alex” takes breaths

My wife and I were having a “yes” … “no” battle, and I was getting tired of saying “no” over and over again.  So I typed a bunch of “no’s” into QuickSilver and invoked the “speak text” action.  OS X Leopard’s “Alex” voice kicked in with a litany of “no’s.”  And then about ten “no’s” in, he took a breather.  No really, he inhaled.  And at regular intervals, he took more breaths.  It was creepy.
