The interviewer says, “I see on your application that you left your last job due to illness. What kind of illness was it?” He replies, “They didn’t say; they just said they were sick of me!”
Explanation: This joke relies on a clever play on words. The interviewer is inquiring about a specific illness, but the applicant humorously interprets “sick of me” as a general annoyance with his presence, suggesting that his coworkers were tired of him, adding a humorous twist to the conversation.
