Jerry walked in on Dave having sex at work!
As Dave zipped up his trousers, Jerry asked, “What the hell were you thinking having sex with her?”
Dave replied, “Well she was just lying there naked, looking sexy and all. What was I supposed to do?”
“For one,” explained Jerry, “you were supposed to be doing an autopsy on her!”
Dave indignantly shot back with “Listen, Jerry, I don’t tell you how to do your job, so don’t tell me how to do mine!”
Jerry just shook his head in disbelief, “Dave, you’ve got to be the worst veterinarian ever.”
