Dont know if this belongs in this topic but I'm a huge JR fan and he is the ultimate (very funny - imo) pedant...
I haven't watched all of the episode yet but I have read his book and seen him live and would recommend him to those of a pedantic nature everywhere - he obviously uses his personality and OCD tendancies and the resulting affect it has on his life as comedy material but the book is more a sad/funny/poignant narrative of him trying to cope with everyday life as an obsessive perfectionist.
A very underrated comic, love him
