You can never be too careful,that's what I always say, and so I wear a hat, or two,in case my hair turns gray.I've thirteen tires on my car,in case I get a flat.I wear my pants size fifty-three,in case I grow too fat.You can never be too careful,I'm sure you'll find it's true.I see the doctor every day,in case I catch the flu.I carry twenty handkerchiefs,in case I have to sneeze,and forty seven bandages,in case I skin my knees.You can never be too careful,so if I take a walk,I tiptoe everywhere I goand whisper when I talk.I hide my money in a box,and lock it up inside Fort Knox.My house is made of bricks and rocks.The front door has a hundred locks.But now I have a problem, see,I'm locked inside without the key.I've lost it and I can't get free.I hid it much too carefully!
