"Ring, ring!"  My alarm goes off.  I get up.  "Ding, ding."  My car starts and I'm off.  "Bing-bong!"  I have new emails.  "Ding!"  The microwave is finished injecting my lunch with radiation.  I run to it like a happy puppy.  "Ding!"  Oh yeah, Outlook reminds me that I have a meeting today.  "Beep!"  Sorry, I was glazed over at the traffic light.  "Beep, beep!"  Cool, Wendy sent me a text message. 

Update (2007-04-12 9:33am):  This is similar to the idea of Pavlov's dog, a phrase "used to describe someone who merely reacts to a situation rather than uses critical thinking". #psychology
