Puns of Steel was an interesting collection of single-panel comics done by Scott Hilburn. I picked up this book solely because it had the word 'puns' in the title.
Even though it was published in 2011, some of the panels still hold up very well. Others, of course, definitely show their age. About one in every 6 panels had me at least snorting in amusement. A rare handful made me giggle. Most made me think "Eh...he must have been desperate that day."
This was a pleasant way to spend twenty minutes. While I don't think I would actually recommend the collection to anyone, if you come across it at your local library, you might as well pick it up and give it a flip through.
