When we had our first con in St. Louis, we discovered a misprint in the program the NIGHT before it opened.
Apparently, someone had printed the movie "Jelly" instead of the movie "Joey" in the program, as a movie that Louise Jamieson was playing in.
Problem was... Jelly was a prominent PORNO movie running in England at the time.
We stayed up ALL night with 50 bottles of whiteout, and lots of volunteers, correcting this problem. ;)
Ah, such fond Convention memories. ;)
