P is for Puns
You Kant Make It Up by Gary Hayden
This is the only book I own with a pun in the title, and the pun itself is the only reason I bought it because it genuinely made me chuckle. I saw this book in Shakespeare and Company, the famous bookshop in Paris, when I was visiting a friend who lived in the city back in 2013. I saw it laughed, and promptly bought it on Amazon when I returned home. 🙈🙈🙈 (Incase this isn't showing up on whatever device you're using, I just posted some monkey emojis covering their eyes because I know how shameful that is!)
I've also never actually read this book 🙈🙈🙈(more monkey faces) but it is full of history's strangest philosophical ideas and according to the blurb is supposedly very funny.
