Mitch Hedberg's quote is a funny method of saying that Bologna is a popular deli meat. He is indicating that it is so popular that even individuals with eyes can acknowledge it. This is a play on the expression "a blind guy might see it," which is used to describe something that is extremely apparent. Hedberg is satirizing the truth that Bologna is so widely known and taken in that it is practically a cliché. He is likewise making a joke about the fact that people with eyes can see the deli meat, instead of people who are blind. By using humor, Hedberg is making a point about how popular Bologna is and how it is a staple in many individuals's diet plans.
