One of my favorite books ever (though not humorous) is The Shell Seekers by Rosamunde Pilcher. It was very "cosy" to read. A funny one that was still poignment was Blessed are the Cheesemakers if you can find it. I was drawn to the title (since I'm a Monty Python fan) and liked it. I don't know if you hate the whole vampire genre, but the Sookie Stackhouse books start off pretty funny. (They are not at all like the series True Blood, which is based on them.) The first one is Dead Until Dark. If you like mysteries but don't want to think very hard, the Stephanie Plum series is laugh-out-loud funny. The first one is One for the Money.
