In 1980 Michigan inventor Lawrence Robinson suggested wrapping an aquarium around a bathtub so that fish lovers can bathe with their pets:

This invention relates to a bathing fixture or tub such as ordinarily employed in the home, which also is an aquarium. The device may be used in the normal manner in the typical home bathroom, but it also provides the unique feature of an aquarium. The aquarium is so related to the bathing section of the tub that a bather will be literally surrounded by the aquarium creatures and/or plants while taking his or her bath.

I wonder what the fish think about this.
