Dental assistant (on the phone): Oh, I hear your dog in the background.
Me (sarcastically): Yup, my little "puppy."
DA: What kind is it?
Me: Uh, it's Roger.
DA: (confused silence)
Me: My 5 year old.
Yup, my 5 year old son likes to pretend he's a dog (that is, when he's not pretending to be a cheetah, tiger, beluga whale, or some other creature), and apparently he's convincing enough that he fooled our friend the dental assistant...
