On more than one occassion...
Speaking of sleeping in weird places, here he is sleeping in the bookshelf. His other favorite spot is inside the shelves of our coffee table.
Another thing he likes to do is jump into the bathtub. He loves water, which is not unheard of for a dog, but most of the small dogs that my family has owned usually don't care for water.
And here he is in the empty bathtub, just begging for us to fill it with water.
