True story. My girlfriend asked me if she needed to rotate the air in her tires.
Yes, she was a blonde!
No need to rotate, but you do need to switch from winter air to summer air in the spring and then back again in the fall.

Speaking of blondes I was walking to a store and noticed a woman trying to unlock her car and obviously having trouble. I stopped to help. She explained she'd been having an increasingly difficult time getting her key fob to unlock her car door it now wasn't working at all. It was obvious the battery in her key fob was dead. However, she was very distraught as she didn't know how to get in the car, and didn't have the money to pay a locksmith.
She also stated that she had locked her keys in the car in the past, and that she was aware that the police department policy was not to unlock doors in non emergency situations. However, she still asked if I knew of a way to unlock her door, without having to spend money on a locksmith.
Now...this was about 25 years ago, well before ignition keys went away on some cars so there was of course a key attached to the fob. Rather than have her call a locksmith, I told her that there were two ways to unlock her door, one at no cost, and one for a just a couple dollars. First, I showed her how the key would fit in the lock and open the door, since it unlocked the door in addition to starting the car. She was amazed. She never knew that the key did double duty.
Second, I explained that they sold new batteries for her key fob right there at the store where she was parked, and I explained the little indents on the key fob where you could open the battery compartment. Her mind was once again blown by the concept of changing the battery in her key fob to get it to unlock the door. She thought she would have to buy a new one. I escorted her back into the store she'd just come out of and helped her select a new battery and replace the old one so she wouldn't have to face the challenge of unlocking the door with a key all by herself.
She was nice enough, but by no means the brightest crayon in the box.
