We are not quite as stupid
At one time I used to do trademark registration. I had one marketing guy who wanted to trademark a phrase consisting of words in common use in the UK, I argued he couldn't, so eventually I just slapped it in and put the rejection notice on his desk.
I now realise I should have trademarked it in the US, where it would obviously have gone through. Words simply fail me on this, I simply cannot find adequate ones to describe the incompetence (or venality, your choice) of the USPTO.
