I was reminded of something very funny the other day:
my youngest daughter used to do this hysterical jump off the diving board when she was younger; she'd hold her arms up in the air, pointed in a V to the sky and would make herself do the "pencil dive". She thought she resembled a pencil, I guess with her arms at a point and her feet together. She would jump straight in, feet first, not arms first, which is how a "dive" should be. I laughed thinking about it. She does an actual dive now.
