Barry Kripke is a plasma physicist at the California Institute of Technology and an antagonist to the four other guys. He is annoying and enjoys mocking other people, which is somewhat ironic given his speech impediment makes him sound like Elmer Fudd. He is not self-conscious about this at all and frequently uses words with l's or r's in them that exaggerate his impediment.He, too, hits on Penny, although he deems her name isn't hot enough, so he calls her Roxanne (which of course comes out Woxanne ). He seems to be aware of his lack of appeal toward women and doesn't help his case by sending crotch shots.
