I don't know if this is funny, or just funny to me because it happened to my husband....
A week ago, my best friend and I went diving at our local lake. We had just returned from Hawaii and had removed the butt-plug from the back of our BCs before flying. She made it the hour and a half from her house to the lake only to find that she had never replaced the plug. So she borrows my husband's plug, who launches into a "pre-flight inspection checklist" tyraid... multiple times since that week might I add :-/
So Friday the husband and I make the 3 1/2 hour drive to Monterey to do some diving at the BW. The morning we are suppose to meet our friends, my "pre-flight inspection checklist" husband informs me that he forgot his regulator! The whole dang set-up! We go to the local dive shop and they do hook him up, but then they tell him their low-pressure inflator hose will not work on his integrated octo. So at this point, I be laughing my arse off that he is out a BC also. Luckily, the dive shop got everything sorted out and my husband was able to dive.
The audacity of it all was when I told him that his mistake was like that of my besties, he responded that all of the equipment he brought was in perfect working order, at least. All right buddy ;-) !!!
