The joke “What do you call a Turkey after Thanksgiving? Lucky.” plays on the cultural tradition in many Western countries, especially the United States, where turkey is the primary dish served during Thanksgiving dinner. Millions of turkeys are consumed on this holiday. In the context of this tradition, a turkey that manages to avoid being chosen, cooked, and eaten on Thanksgiving would indeed be considered “lucky.”

In “Once Upon a Time in Hollywood,” Rick Dalton, played by Leonardo DiCaprio, makes a pun between “Bengal Lancers,” a real British cavalry regiment in India, and “Lancer,” the name of the fictional TV show in which they’re acting. Dalton mispronounces “Bengal” as “Bangel” to force a connection with “Lancer.” He thinks it’s ironic that the Lancer dude was in a company called Bangel Lancer…while in India.
The humor isn’t in the joke’s cleverness but in its awkwardness. Dalton, trying to be witty, actually reveals his lack of sophistication. The joke serves to showcase Dalton’s character, a fading Hollywood actor desperate to reclaim relevance, often resorting to misplaced humor in inappropriate situations.
Also in the UK, Bengal Lancer is English slang for someone who is unqualified for a job.

The joke “What do you call ghost poop? Boo boo” plays on the double meaning of the word “boo.” In one context, “boo” is a sound that ghosts are stereotypically known to make, often used to scare people. In another context, “boo boo” is a child-friendly term for a minor injury or, in some cases, feces.

The joke “What does a redneck do on Halloween? Pumpkin” is a play on words that uses a double entendre. The word “pumpkin” is a homophone for “pump kin,” with “kin” being a colloquial term for family or relatives. The joke plays on stereotypes about rednecks, suggesting a taboo or inappropriate relationship with family members. The humor arises from the unexpected answer to the question, as the listener is initially led to think of “pumpkin” as the orange gourd commonly associated with Halloween.

The joke “Why are vampires so easy to fool? Because they’re suckers” plays on the double meaning of the word “suckers.” In the context of vampires, “suckers” refers to their characteristic behavior of sucking blood from their victims. However, in colloquial English, a “sucker” is also a term used to describe someone who is gullible or easily deceived. The humor in this joke arises from the clever overlap of these two meanings. By suggesting that vampires are “suckers,” the joke is making a playful connection between their blood-sucking nature and the idea that they are easily fooled, blending the supernatural element with a common idiomatic expression in a humorous way.
