My buddy Dennis has had a couple of interesting weight related incidents. Dennis is very bouyant by himself, with 14mm of Henderson Gold Core, he needs a metric tonne of lead to submerge. His 40 lbs would fit in his Oceanic Chute II BC, but it was a bear to handle, and he had trouble loading the weight pouches.
During our final OW check out dive at Lover's, we were supposed to submerge at the dive float, and then swim along the bottom, navigating to the shore. Dennis and the Assistant Instructor descend rapidly to about 30 feet, with maybe 10 foot viz at best. I am following slowly as I need to equalize and descend slower than he does. When I get down, I can't find them. Brief search, then head up to locate them. He is swimming at the surface, with his first stage at his ear. I tell him that something looks wrong (dive 4 remember) and he says that he lost a weight. I am thinking he means one of the 2 lb clip-ons the instructor added, so what is the big deal?. After swimming to shore, he tells me he lost his weight pouch with 15 or 20 lbs in it. While descending, it simply fell out. We assume that the funky "locking mechanism" (and I use that term loosely) just wasn't really locked in. When the Instructor swims to shore, he is towing the dive float (with the extra clip on weights etc etc etc) and a Lift Bag. We had no idea what was going on. He hoists the lift bag to show the Oceanic weight pouch and says "did you lose something?".
It turns out that he was at the bottom unscrewing the anchor screw for the dive float when my buddy's weight pouch landed on his back. He simply floated it back to shore. Saved my buddy a bit of hassle and expense.

My buddy's best one was a couple months later on a private boat dive in Monterey. He was tired of wrestling with the 40 lbs in the BC, so he got a weight belt to carry some of it. We were on Greg's boat, our much more experienced friend. That dive was Dennis and Greg and I was minding the boat. Greg always wanted to be real "helpful" but sometimes the results were a little different.
Dennis surfaces, and I reach down to accept gear to be handed up. He is hanging at the platform, trying to catch his breath and gather himself. He has his legs spread real wide, because he has no hips, and the weight belt is trying to head south. He is struggling to hold on, and to figure out how to yank the weight belt back up high enough to stay on him. I am willing to help, but basically worthless from my location. Greg is still barely under the surface watching, but not understanding. Greg decides to "help" by removing Dennis' fin. Dennis is yelling at me that Greg is yanking on his leg, and it is going to make him drop the weight belt. Of course Greg can't hear us because he is underwater. He finally surfaces to hand me the fin, and we tell him to stop helping, because Dennis is struggling with the slipping weight belt. Greg drops the fin, re-submerges to assist with the weight belt. I almost go in myself reaching for the sinking fin. Again, he can't hear us because he is underwater.
It all was resolved eventually, but now Dennis was minus one Black Apollo Bio-Fin. Greg finally surfaced again, realized that he had dropped the fin, and that it did not float! He searched the bottom briefly with his remaining air before we gave up.
Now Greg knows what my mother has always pounded into our heads since I was a very young child; "Make sure your help is wanted before you give it!".
Of course Greg was sincerely trying to help, and he feels bad. Our local dive shop was willing to sell Dennis a single new fin because lots of people lose them out here. Everything worked out okay, and we have a funny memory of the day with Dennis spread-eagle screaming for Greg to stop helping.
Wristshot
Epilogue: Dennis has since bought a DUI Trim System and a Zeagle Ranger. The DUI holds some of the weight, and it can't fall off. The Ranger is easier to load the weight pouches, and never releases.
