We used to tell this joke at the computer company where I worked.
The sales people would often go out and sell a large complex computer system to a customer, then leave us technical people to sort out how to get it all to work togther.
Meanwhile they went off to try to sell another computer system to another customer.
So we likened them to the man who found the bear, then rushed off to get another bear, leaving the poor guy in the cabin to skin that one.
