When we've been to Egypt, my wife and I were doing snorkeling. At some point a crab decided that my wife's head is a nice island to take some rest. I assure you it is very difficult to understand that somebody is screaming when she has snorkeling tube in mouth. Next challenge is to understand why (because Mr. Crab was kind of black on dark hair) so it was pretty hard to notice. For long 15 seconds (half of life according to my wife) I didn't understand what's going on and thought she is just really impressed with beautiful corals and fish. Nobody wants to be thrown in water in the middle of the sea. So when I took it off her head it tried to swim back on (obviously because it was very nice island). And it succeeded! Have you ever seen in a cartoon like somebody jumps out of the water in the middle of the sea? I've seen it in real life! This time I was pretty sure that she is screaming. And why she is screaming. I had to politely ask Mr. Crab to go away, but he refused. After some negotiations I took it off and had to dive down to the bottom and leave it here, so it doesn't get back on that lovely island. Since then she consider crabs as mortal enemies. Photo of a slaughtered enemy and my lovely island attached.
