I found this one on Reddit and have been laughing so hard. I don't think I realized how much a curled-up dog looks like a giant furry bagel. (Would a poppyseed bagel be a dog with fleas? I have so many questions about this metaphor.)
Anyway, try to answer 'bagel' or 'dog' to these pictures as fast as you can. It might be more challenging than you'd think!
