I've always loved the Far Side by Gary Larson, maybe because my sense of humor has always been a little "off"?  Anyway, I used to have a copy of "While their owners sleep, nervous little dogs prepare for their day." here.  Whether or not it is infringement of  copyright laws or legal and fair use is grey area, but it appears Gary Larson doesn't approve of any of "his children" being out running free on the web, so I am removing the cute little cartoon of the wienie dog filling his cup with expresso.  Boo hoo.  If you want to see it for yourself, pick up a copy of Cows of Our Planet.  Here's the website I found with Gary's sentiments on it and a little about copyright laws.
