So it turns out that if you search for 'porcupine' in Google Images, you tend to get 1/3 pictures of porcupines (Mostly old world), 1/3 people and things that look vaguely like porcupines, and 1/3 dogs that don't know when to walk away.

I know that adding a -dog helps a ton in the search, I just think it's kind of funny, and a bit sad. A porcupine's defining feature are its quills, sure, but do you have to be so focused on how they look sticking out of something's face? XD
