Excellent photo! The only thing missing (imho) is that to better fit the challenge topic, photo needs to rely less on the title you give it. I had to read the title to understand what the humor is about. Some other pics did not need the reinforcement of the title, and only because of this I give it a 8. For some other topic, I would have went with 10.
the title is a little far fetched but the shot and idea is good IMO u could've just called it something elce (like- "Did I forget my nut?") that would make it less of the humanised and make it more just forgetful squirl and it would've been just as funny if not more.(imo)
