Is there a book called “mathematical pranks”?

A friend told me that there is a book named something like "Mathematical pranks" which lists tricks to mathematically fool and prank your friends like fake and false proofs that look ok and so. But I can't find the book. Do you have an idea what I'm talking about?

There is a book called Mathematical Cranks (Underwood Dudley). But it is not about how to shortsheet a bed at Math Camp. – André Nicolas Jul 20 '13 at 14:32
Your friend could also have been pulling a prank on you – cats Jul 20 '13 at 16:34

Although there probably is no book with that title, Linderholm's Mathematics made difficult is exactly that: a collection of pranks.
As the title says, it consists of absurdly sophisticated proofs of trivial or easy results.
For example here is the Wikipedia page reproducing the proof that $2$ is a prime number.

There also are interesting asides:
On pages 37-38 you will read " It is not correct in logic to prove something by saying it over again; that only works in politics, and even there it is usually considered desirable to repeat the proposition hundreds of times before considering it as definitely established "

On page 156 called A parenthesis on the sex life of brackets you will learn about "the special liaisons which occur chiefly in France: monstrosities like $[a,b[$ in which two brackets of the same sex join horribly".
Anyone aware of the recent law in France authorizing same-sex marriage (just Google "Le mariage pour tous") can only stand in awe before the eerie prescience displayed by the author.

My analysis teacher uses $]$ for $($, and he had explained that that's to distinguish ordered pairs and intervals, which made sense to me. So I changed my notation accordingly. By your reference I now know the background of the notation, since he was educated in France. – A. Alp Uzman Mar 6 '15 at 17:45
