Two women are visiting with each other in a small, tidy living room and drinking tea.  Seen through an archway is a man holding a hammer and looking intently at stone wheel that's as tall and wide as he is.
It's unusual for someone to chisel a large stone wheel in their foyer.
Why did the man make this huge stone wheel in his house?
Try to look surprised.

A joke about humoring the man's work --- the two women are going to pretend to be impressed/surprised when the man brings in his new invention: but the wheel is an already widely known and used, so to be polite, they need to pretend to be surprised by his ingenuity. It's funny because the man somehow didn't realize this invention was novel, and hints that sometimes people figuratively (and here, literally) reinvent the wheel.
