I thought of, "Those waves don't look that big..." as we watched set after set come it at 3-5 feet on the Oregon Coast (a long time ago). During the dive, they kicked up to 15-20 feet, and we stayed in the ocean for over 3 hours until the Coast Guard came out and got us. Thank goodness for girl friends and a buddy line (belt with "D" rings, 4' section of 1/4 inch nylon rope with brass snap hooks, positively maintaining the buddy system), a red white-water kayaker's helmet with white stripes that could be seen from several hundred yards, and a good buddy.
But the more I thought of it, the more the realization came that when the wave rolled us, there were no last words. The blasted regulator and sea water took care of that. We really didn't talk until we'd gotten the situation under control.
So my conclusion is that, for divers, there really are no "famous last words." That can occur in non-serious situations, but when it really gets rough, the words just won't come out.
