how are Harris and uncle podger similar?

It would seem like they share similar traits. J. compares Harris to Uncle Podger because both of them have difficulty performing basic tasks without making mistakes.Uncle Podger was unable (or unwilling) to tackle a task alone. He would send everyone off to do his bidding, make a mess of things, and blame it on everyone else. Then it would start all over again, with everyone at his back and call. This would go on for quite awhile, and each time there would be a mistake, and each time someone else would step up to help. In the end, Uncle Podger would cite how easily things were done, and his wife would comment that she'd stay with her mother during the next project..... a comedy of errors.
