A man walked into a mental institution one day and was taken on a tour. The tour saw one cell where the man was beating his head against the padded walls. He kept saying, "Linda, how could you do it? Linda, how could you do it?" The guide explained that the man was in love with Linda, and when Linda jilted him, he drifted off into the ozone. He couldn't handle it.

They went to the next cell, and there was a man saying, "Linda, Linda, how could this happen? Linda, Linda."

The visitor said, "Who's he?"

The guide said, "He's the man who married Linda." That's the myth of the greener grass.
