31. Rubber chicken parking sensor
If you have multiple vehicles and don’t know how to park them front-to-back without crashing, there are sensors you could use to prevent such a thing from happening. However, sensors can be expensive, and they’re single-purpose tools, so you won’t get much enjoyment when using them outside of your garage.
What you can do instead is purchase a cheap rubber chicken toy and use that as a squeaking alarm to tell you when your car is at a safe distance from an object while parking. After you’ve parked correctly, you can take the chicken back inside and have a squeaking good time playing with your pet dog.
