There is no such thing as childproofing your home 2. If you spray hairspray on dust bunnies and then run over them with roller blades, they can ignite. If you hook a dog leash over a ceiling fan, the motor is not strong enough to rotate a 42-pound boy wearing pound puppy underwear and a Superman cape. It is strong enough to spread paint on all 4 walls of a 20x20 ft. room.
Baseballs make marks on ceilings.
When using the ceiling fan as a bat, you have to throw the ball up several times before you get a hit. You should not throw baseballs up when the ceiling fan is on. A ceiling fan can hit a baseball a long way. A magnifying glass can start a fire, even on a overcast day. If you use a waterbed as a home plate while wearing baseball shoes, it does not leak, it explodes.
