The joke “Did you hear about the man who filled his inflatable girlfriend up with helium? And now she’s playing hard to get!” employs humor through wordplay and a whimsical scenario. The key element is the use of helium, a gas known for its property of being lighter than air, causing things filled with it to float or rise. The term “inflatable girlfriend” humorously refers to a blow-up doll, often a subject of jokes relating to loneliness or substitute companionship. The phrase “playing hard to get,” typically used to describe someone who is intentionally acting unapproachable or aloof in a romantic context, is humorously literalized here. When the man fills the inflatable girlfriend with helium, she physically floats away, making her literally “hard to get” due to her newfound buoyancy.

The joke “Knock, knock. Who’s there? Little old lady. Little old lady who? Wow! I didn’t know you could yodel” is a play on words involving the typical format of a knock-knock joke and the art of yodeling. Knock-knock jokes usually follow a predictable pattern, where the punchline is a pun based on the name or phrase spoken by the ‘knocker’. In this joke, “Little old lady who?” sounds like the person responding is attempting to yodel, as “who” resembles the sound of a basic yodel. Yodeling is a form of singing which involves repeated and rapid changes in pitch between the low-pitch chest register and the high-pitch head register.

The joke “If April showers bring May flowers, what do May flowers bring? Pilgrims.” plays on the dual meaning of the word “Mayflower.” The first part of the joke is a common proverb: “April showers bring May flowers,” which means that a period of discomfort can provide the basis for a period of joy and pleasure. It typically refers to the rain in April leading to the blooming of flowers in May.
The punchline, “Pilgrims,” is a clever twist. While listeners might expect a continuation of the botanical theme, the joke instead refers to the Mayflower, the historic ship that transported the first English Puritans, known as the Pilgrims, from Plymouth, England, to the New World in 1620.

The joke “Where can you buy chicken broth in bulk? The Stock Market.” is a play on words involving a double meaning of the term “stock.” In one context, “stock” refers to chicken broth or soup base, which is a common cooking ingredient. The setup of the joke leads the listener to think of this culinary meaning, as it asks about buying chicken broth.
However, the punchline shifts to a different meaning of “stock,” referring to the financial stock market, where stocks (shares in companies) are bought and sold.

The joke “What do you call a rabbit with fleas? Bugs Bunny.” is a humorous play on words involving a pun, which relies on the double meaning of “bugs.” In one context, “bugs” refers to small insects, such as fleas. This sets up the listener to think about a literal situation where a rabbit is infested with fleas. However, the punchline shifts the meaning to a reference to “Bugs Bunny,” a famous animated cartoon character known for being a clever and mischievous rabbit.
The humor arises from the clever wordplay linking “bugs” (the fleas) with “Bugs Bunny” (the character). The joke creates a comical association between a real-life scenario (a rabbit with an infestation of fleas) and a well-known cultural icon, blending the literal and figurative meanings of the word “bugs.”
