Q: What did Cinderella say when her photos did not show up?
A: Someday my prints will come!
Explanation: The phrase would be, “Some day my prince will come.” Cinderella is waiting for her prince charming to sweep her off her feet. If she sent in some pictures to be developed she would wait for her prints to be printed, her pictures to be printed on paper.
This joke is funny because the word “prints” and the word “prince” sound the same. But they have very different meanings
Q: How did Ben Franklin feel about discovering electricity? 
A: He was shocked!
Explanation: First of all, Ben Franklin did not discover electricity (learn more about the electricity here). What he did was an experiment to prove that lightning was electrical. It is a good thing he wasn’t killed! Anyway, “to be shocked” is to be surprised. “Shocked” is also what you feel when a bit of electricity enters your body. This joke is funny because of the double meaning of the word shocked.
Knock knock!
Who’s there?
Queen
Queen who?
Queen yourself, I can smell you through the door.
Explanation: This knock-knock joke comes from GRIN:) at http://goodriddlesnow.com/jokes/by/knock-knock-jokes.
It is funny because it plays on the similar sounding words “queen” and “clean.” The listener expects something related to a queen knocking at the door. Instead, the listener hears an order to get “queen,” rather “clean.” It is as if the speaker does not speak clearly, like the cartoon character Elmer Fudd who is always outwitted by Bugs Bunny.
Q: Why can’t a nose be 12 inches long? 
A: If it was, then it would be a foot!
Explanation: In the standard system of measurement, the system that is used in the United States, 12 inches equals one foot (about 30 cm). A foot is also a body part, just as a nose is a body part. This joke plays on the double meaning of the word “foot.” And of course, a nose cannot be a foot!
Q: Where do you find a birthday present for a cat? 
A: In a cat-alogue!
Explanation: A catalogue is magazine that shows things that someone can buy; you might see a clothing catalogue, an electronics catalogue, … You can see images from a 1945 Sears catalogue here. And from a 1980’s Sears catalogue here.
Of course “catalogue” begins with “cat” and that is what makes this joke funny.
¡Happy Birthday to E. A. S.!
Q: Why didn’t the skeleton go to the ball?
A: He had no body to dance with!
Explanation: “Ball” is a synonym for “dance.” So, why didn’t the skeleton go to the dance? Well, because a skeleton is all bones and nothing else, a skeleton does not have a body. That is, he has no body. When you put those two words together you get “nobody.” This joke is funny because it plays with the words “no body” and “nobody.” If he had nobody to go to the dance with he would go alone. In this case he had “no body.”
Q: Why did the lady sing lullabies to her purse?
A: She wanted a sleeping bag!
Explanation: Lullabies
are the songs that caregivers sing to babies at bed time; the hope of singing a lullaby is that the child will fall asleep. The words “purse” and “bag” are synonyms; a purse is a shoulder bag that women use to carry their items. If the purse falls asleep, the bag would be sleeping. A “sleeping bag” is also the term used for a person-sized bag lined with warm materials that is used for sleeping, especially on camping trips. This joke plays on the phrase “sleeping bag” and the double meaning created in the joke.
