Something is not quite right with this picture

Yeah @creativedragonbaby gave me the exact same reaction when I gave the answer to a maths joke >:( Some people look to the comments for answers ya know...

Well it's not that difficult. Also I didn't mean that one. I said it was fine. That "criticism" was a joke. You can look at the comment. I didn't even edit it, that was a joke from the start.

I didn't get this one

Oh this time it wasn’t a joke

Where specifically is the dude's third hand? I see one by his side and one sort of on the girl?

....and then... you know... his hand on the other side of his body.

Girl's shoulder, below that in between them, on the right.

I assumed that was the girls hand

In the middle you can see it has a grey sleeve

Huh. Just thought it was the lighting and resolution. I see what you mean now...
