"Okay, first, you can't say BLESS YOU BOYS. That's a Detroit Tigers' slogan, and one that was only used really in 1984."Stewart, the Saints have been using "Bless you, boys" as their slogan for years. A local TV station even uses it in its advertisements--part of its "we're all about New Orleans" theme (see graphic). I can't say how long the slogan has been used here, but I've heard it as part of Saints fervor for decades. The Saints have been around for 40 years--I remember when the team first began playing--and "Bless you, boys" seems always to have been echoing through the airwaves. If I had time, I would see how far back an online search could trace the Saints' use of the term. (I love to pursue academic questions.)
Of course, it's also possible that Saints fans "borrowed" the phrase from the '84 Detroit Tigers. After all, it's a slogan that goes perfectly with our team's name, yes?
Thanks to both Stewart and Sidney for commenting and sending good wishes.
