Ok.. Ok... so not funny. Let's have the mods move it to the 'Humor' forum. Perhaps that will give the posting a different context.
It became a tradition for our groups returning from Grand Cayman to raise their hands during the return flight and show off their stingray hickies. It never got reported in the news. But our divers weren't billiionaires.
I'm not an instructor anymore but I did spend a fair number of years as a full time instructor. So rather than spread dangerous misinformation that could lead to the slaughter of innocent stingrays or the closing of stingray dives, I'd like to ask the mods to move this to the Humor section.
Sorry if I offended. In the future, I'll keep my humorous posts topics focused on my better material, sex and underwater farts.
