Charlie was fixing a light switch and found that he needed a new cover plate, so he sent his wife Mary to Home Depot.
At Home Depot, Mary saw a beautiful tea pot while she was waiting for Walt, (the manager) to finish waiting on a customer.

When Walt was finished, Mary asked..
-How much for that tea pot?
Walt replied,
-That's solid copper and it costs $300.
- My goodness that sure is a lot Mary exclaimed. Then she proceeded to describe the plate cover that Charlie had sent her to buy, and Walt went over to the next aisle to find it.

From the next aisle Walt yelled,
-Mary, you wanna screw for that switch cover?

Mary replied,
-No, but I'll blow ya for the tea pot.

This is why you can't send a woman to Home Depot
