Calvin and Hobbes by Bill Watterson for March 17, 1993
Transcript:
Calvin: You know, there must be thousands of animal species, and of all of them, only humans wear clothes. Isn't that weird? I wonder why other animals don't wear clothes. Hobbes: If our naked pink butts showed, we probably would. Calvin: Our butts are just fine!
Apparently, Calvin’s not familiar with the spider decorator crab. It attaches pieces of organisms such as sponges and seaweed to its shell, disguising itself from predators.
