Have you ever struggled to pass the human verification on websites? [I Ask Questions]

I failed one recently when trying to send an Outlook email. The system displayed a bunch of mazes with mice and cheese, and asked something like, "Which mouse can't reach the cheese?" Individually, the challenges were doable. Problem was, it makes you do a bunch of them, and doesn't really give much time for it. I think I'm decent at this sort of thing, but I had great trouble with it.
