What is the silliest name you gave to a pet?

I had a student who desperately wanted a dog for Christmas. She went on & on about it from Halloween until Christmas break. When I saw her for the first time after the new year, I greeted her but she looked pretty grumpy. I asked Grace what was wrong. She just frowned. Her father told me she got a new pet for Christmas. A hamster. I smiled & asked her what she named her new friend. She replies “Dog”, with a look to kill. 😅
