There is no such thing as child-proofing your house. If you spray hair spray on dust bunnies and run over them with roller blades, they can ignite. A 4 year-old's voice is louder than 200 adults in a crowded restaurant. 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, however, to spread paint on all four walls of a 20 by 20 foot room.
Baseballs make marks on ceilings.
You should not throw baseballs up when the ceiling fan is on. When using the ceiling fan as a bat you have to throw the ball up a few times before you get a hit. A ceiling fan can hit a baseball a long way. Brake fluid mixed with Clorox makes smoke, and lots of it. A six year old can start a fire with a flint rock even though a 36 year old man says they can only do it in the movies.
