I used to work for Sears portrait studio when I first got out of high school. One day, during the "selling" portion of the job, I took all the photos out of the envelope and displayed them upside down on the desk in front of the customers, with a "Oh, no.... this order, too. The lab has had problems with printing some orders inverted lately, and it looks like yours is one of them."
About a quarter of the people asked about getting them reprinted or something. Funny, but kind of sad, too!
The rest got a good laugh...
And yes, I shot the phone that way....
