What was the worst CAPTCHA you had to do?

I had one the other day where it asked me to select all of the mountains or hills so I did and it told me “no please select all of the photos” as if I missed one.

The rest of the photos were of roads and stuff, but one of them had a bridge that had a slight grassy incline on the sides of it which I wouldn’t classify as a hill or mountain by any stretch of the word, but maybe it thought it was? and sure enough it went through. I think it just didn’t know what a hill was.
