Trying to find a story anti-joke I heard once from a coworker

The story went something like this but I can’t remember the exact punchline, please help me out if you know where it’s from or could write the joke well! There’s an extremely skilled carpenter father who has a son but loses his wife in childbirth. Then the son grows up and gets cancer young so the father has to sell all his valuable sculpted pieces of wood to pay for the surgery including a special wooden globe he made for his son because his son is his whole world. Then his son tragically dies and the father wants to go find the globe he made as a memorial to his son, he looks all over in different stores but is distraught until going into the final store in town where the shop keeper leads him to a back room and they talk for a minute and then the shop keeper makes a stupid pun that turns the whole story joke on it’s head It made me laugh so hard but now I can’t remember, please help!
