Listen up, buttercup! The joke is comparing a job to a wife. The punchline implies that after being married for 5 years, the wife, like a job, "keeps sucking". "Sucking" in this context is used as a double-entendre, suggesting both unpleasantness (like a bad job) and oral sex. Are you following, or should I use smaller words?
