Larry, How about a category on the forum entitled:
"SAFE, Practical Scuba Jokes" or, possibly, "Fun and Games - Scuba Related"
For those of us who have been diving many years, we know that safe, practical joking with our fellow divers seems to go with the territory. It's always interesting to hear about some of the practical jokes that have been done on fellow divers.
To start the flow, here are a couple of my favorites:
1. Before a dive, put food coloring (like blue) in someones' booties. When they come back from a dive and take off their booties, their feet are Blue. Better yet, put a different color in each bootie!
2. Take some Ambesol or Orajel (topical anesthetic) and put it all around someone's mouthpiece. They'll wonder why their lips and tongue went numb during the dive.
Thanks, Kent
