The monkeys you ordered hosts a ‘literal caption’ for The New Yorker caption contest art.
For the above image they went with, “How did Spot get opposable thumbs?”. Not my caption of choice since it’s not very literal or real, given the talking dog and their knowledge of opposable thumbs. Rather it reads more like an actual caption contest winner. Plainly speaking it is not very good for a literal caption.
I would have gone more along the lines of, “this dog suit is really freaking these mutts out” or “A typical summer day on The Island of Doctor Moreau”.
