Nikko did that once. I left the chair out and he was right on top of the table when I came home from work. He was scared and shaking so I don't know how long he was up there. He couldn't figure out how to get down. And as for the "teacher/dog ate homework story" here's a funny twist. My husband was grading a bunch of his student's compositions and he went to the kitchen for a bite to eat. The window was open in the dining room and apparently blew some the sheets onto the floor. Well you can guess what happened next. Nikko tore them to shreds.

Needless to say, my husband was upset but I couldn't stop laughing. Imagine a teacher having to tell the kids that
his dog ate
their homework...
