U.S. Patent No. 5,901,666 (.pdf)
Every hamster owner out there wants to take their hamster out for a walk in the park, but how do you do that? With an article of Pet Display Clothing, of course! Using soft, vinyl "pet receiving" tubing, you can make a vest that puts your hamster, rat, mouse or other rodent on display for everyone else at the park to marvel over. You could even wear your vest to a party and be all like "Yo, any gangstas wanna check out dis here HAMSTER?" Oh, you'll be all the rage!
