Any fiction that has made you laugh hard, long and often?
Most of Kurt Vonneguts stuff gets a wry smile, but the only book that has made me laugh out loud is Infinite Jest by David Foster Wallace - one-liners, set-pieces and character sketches. Funny as hell.
Not read Stewart Lee's made-up book yet.
Also, anything by Martin Amis or Ian McEwan normally makes me chuckle, but only at that the bits that aren't meant to be funny. Especially "London Fields" with its uncanny premonition of the career of noted "Mockney" Damon Albarn.
