Take a picture of a couple that look most like The Original Taskmaster and His assistant.
Update: Here are some new lookalikes!

I’m not very good at looking at people, but I think that this (below) is a mirror image, so the one on the left in the right picture is the same as the one on the right on the left picture
(because they’re the small ones) and vice versa. Other than that, the only difference is that one chair doesn’t match.
