My favorite reading experiences often occur when a friend with a good (if twisted or dry) sense of humor introduces me to an author I've never heard of. The same friend who introduced me to the comic genius of Peter DeVries recently emailed me his opinion of The Third Policeman. I quickly devoured that book laughing the whole way through, and then I borrowed At Swim Two Birds from my local library. Circumstances prevented me from starting it until right before it was due, and (DRAT!) someone had placed a hold on it. So I ordered this collection.
Two days later, I was happily savoring every page of what may be the most complete comic novel I've ever read. It helps that I seem to have been born with the same desire to poke at anything and everything including structure itself that O'Brien (or O'Nolan) was. What he does is pure genius and can be compared to someone building a house of cards defying previously defined laws of physics and structure in hopes of imploding the whole thing. When it doesn't, he finishes the novel with the ultimate and abrupt comic anti-climax.
I have since moved on to reading A Pour Mouth, originally written in Irish. Even though, I'm certain much of the humor is directed at those who've read (and been bored by) the other Irish literature parodied by this work, I have found this one to be funny as well.
I have been so moved to tears (of laughter and otherwise) by these novels, that I have played them forward to another friend by ordering him a copy as well.
If you like A Confederacy of Dunces, Monty Python, and the like, you will find elements of At Swim Two Birds which have been copied and have influenced these works.
