Bidepdalism is so overrated. Long gone are the days when humans can crawl around on all fours all day and not have a sore back after about five minutes. I know that walking on two legs is more advantageous evolutionarily, but I don't really care! I would love to walk in someone else's feet for a day, and that someone else happens to be a dog.
Despite my desire, I don't think I'd thrive in a Shaggy-Dog-type situation where your human mind gets transported into the body of a large fluffy animal. I could never spell out "I AM DAD" with Scrabble as Tim Allen so brilliantly did. I'm not confident I would be able to come back to being a human when necessary, and I'm not ready to lead the rest of my life as a Shaggy dog. If you are bipedal and love quadrupedal species, these animal memes will suit your fancy.
