If we're talking about Promotions gone awry, this is baseball related, but I remember a ad by the Blue Jays for opening day, with the tag-line something like
"A perfect excuse for calling in sick"
MAN the business community jumped the Jays with that ad, suggested they were endorsing missing work to catch a baseball game, and how it wasn't right.
Funny stuff.
As far as hockey, I remember a friend of mine said they had tickets to a playoff game between Leafs and Kings in 93- I got so excited I went down, and what he meant was tickets at the Skydome(now Rogers Center) to watch the game on the Jumbo Tron!
They still packed the place though-A memorable night for the wrong reasons
