Possibly you’re thinking of Raymond Smullyan’s To Mock a Mockingbird, though its topic is combinatory logic, not set theory.

	That one was a lot of fun. It takes you all the way to Godel's incompleteness. – Ross Millikan Jun 14 '12 at 12:46
	Yes, thanks! Is there a similar book like this to intro in Category theory? – drozzy Jun 14 '12 at 12:58
	@drozzy: I’m not aware of one. There’s definitely not one by Smullyan. – Brian M. Scott Jun 14 '12 at 13:13
