Right when I saw this thread, especially when I saw more of an interest in lighthearted works, I immediately thought of Good Omens by Terry Pratchett and Neil Gaiman. That that just leads into the Discworld series of Pratchetts, and I would strongly recommend American Gods, Anansi Boys, Neverwhere, and Stardust by Gaiman. All every good reads.
Also I have to back what other people said about Jim Butcher's Dresden Files series. It is currently my favorite series of novels and I typically re-read many of them each and every year. Harry Dresden is one of the few characters that will make me laugh out loud while I am reading. I will say that Storm Front (the first novel) is probably the worst one, but if you try it and enjoy it at all, you'll love the rest of the series.
For a more fantasy bent, try Goblin Quest by Jim C. Hines. Especially for anyone who as ever played Dungeons and Dragons, it is hilarious to see a typical dungeon crawl from the POV of a goblin who lives there. It has a lot of role-playing tropes, but not so bad as to turn off a non-RPG reader, in my opinion. And if you enjoy it, you can read Goblin Hero and Goblin War to finish off the series, though the first one stands alone quite well.
