Without Feathers by Woody Allen

 Much like Getting Even this collection of short works from a few decades ago is overflowing with 'smart-funny.' Very entertaining and intelligent, with ingenious material and amusing deadpan. While both excellent, I think I like Getting Even more due to some philosophically oriented jokes. That said, Without Feathers' has The Whore of Mensa (where a man solicits not sex, but intellectual conversation, from a call-girl), which is famous for a reason.

Highly recommended.
