Captchas can be downright infuriating when you're in a hurry. The ones with Street signs and store fronts alway seem to get me as they use very ambiguous pictures. Does the pope or whatever the sign is mounted to count? Do they consider any non residence a store front?

The ones with text are a bit less frustrating to me (sometimes). I've never seen one like what you've shown in this post. Some of these are hilarious.
