Midvale School for the Gifted
By Gary Larson
Design of Everyday Things reminded me of this cartoon.
update: It took him 4 years, but Gary Larson finally forced flickr to take down the cartoon. You can find another copy of it here: www.google.com/images?q=midvale+school+for+the+gifted
Here's a note from Mr Larson about the subject: www.creators.com/a-note-from-gary-larson.html
