Here are some bad puns that are to do with data types. I’m sorry. Comment down some of your own concoctions!
- What does a programmer say when they is accused of lying? I promise I’m not boolean you!
explanation of the puns
“Fooling” sounds very similar to “boolean”, the latter being a data type commonly used when programming. Yes I will be explaining each and every pun. Yes, these puns are not very good at all, I’m not a professional comedian.
The one in the title is a play on words, as “Charlotte’s Web” is a book that can be represented using a series of strings, a data type commonly used for storing words and letters, while a literal web is made of strings of silk.
- You try to pay with $100 of Monopoly money. in a supermarket. The cashier tells you that it’s unfortunately not real.
explanation of the pun
Monopoly money does not have cents and is made of whole numbers, so it is an integer value, not of the “real” data type!
- What would you call fuel made of alphabet soup? CHARcoal!
explanation of pun
The data type char stores characters, like the letters of the alphabet. This is a play on words with the word “charcoal”, a common fuel used in barbeques and such.
- How do Japanese programmers read arrays? By decrementing from -1!
explanation of pun
Many Japanese texts read from right to left rather than left to right. Reading an array in reverse other would start at -1, getting the last item in the array, and the index would decrease from there. This is in contrast to the non-reverse order of increasing the index 0/1. (Of course, Japanese programmers don’t actually read arrays like this usually)
not related to data types, but just came up with it as I was typing this:
f. What did the Python user say to the C++ user when they spilled coffee on their laptop? OOPs!
explanation of the pun
Python uses object oriented programming, or OOP


These make no sense.
“Boolean” does not rhyme with “fooling,” or even “foolin’.” Maybe “bullying.”
Integers are real numbers.
How would you make a dry, solid fuel from soup?
Array index -1 is almost always out-of-bounds on an array.
f. C++ is far more suited for OOP than Python.
Also, who counts “2, 3, 4, 5, f?”
