Jazz Age Puns

My Dad and I were working on outing up a fence together in the backyard, and he was changing the blade on a electric saw he had. He called me over so I can learn how to change the blade (so later in life I can be a proper handyman and all that jazz), except the electric saw he was using was extremely old and very outdated. So I told him, "Dad I really don't think I need to learn that as I doubt I will ever use that." To which he replied, "I thought the same thing when I was your age, then they took all my slaves away."
