The Pregnant Pussy

This lady asked the veterinarian to come to her house to see what was wrong with her cat—no, no, no, I mean, meow, one of them kinda cats
And the doc came by her house, you know, because she paid the fees, and doc gave the cat a third examination and told the lady the cat was pregnant
Lady said, "But doc, that's impossible," she said, "I keep this cat on a chain every time I go out, I keep her on a chain, she couldn't be, she couldn't be pregnant"
Just then, a big tomcat crawled out from under the couch, a dark-lipped big cat
Doc said, "Well, what about him?"
Lady said, "Doc, don't be ridiculous, that's her brother"
And another thing—thank you very much, I like to see you folks laugh
You know, a lot of geniuses are conceited, I'm not
