AS MUCH USE AS A CHOCOLATE TEAPOT

Describing something (or someone) as “a chocolate teapot” is another way of saying that it is (or they are) useless.

 This video from Metro news demonstrates how useless a chocolate teapot is. 😃

 Examples of use:

 “He just crept around in the background and that was it. He was as much use as a chocolate teapot.”

 “I had never done anything like an escape room before so going into it, I thought I’d be about as much use as a chocolate teapot.”

 “A rechargeable battery is as useless as a chocolate teapot without a charger.”
