There are so many good ones, I have to pick at random:
I was sitting by the fire, puffing on a pipe, still nursing a hangover from the ale-fest the night before, when HE walked in.
He had a long white beard, a magical staff, and legs that youd like to eat on toast.
"Are you Frodo Baggins," he intoned.
"I might be," I said. "Who's asking?"
"My name is Gandalf, Mr. Baggins. And I need your help."
I looked him over. "Lots of people need my help. What makes YOU special?"
"Well, Mr. Baggins... there is a certain piece of jewelry. If it fell into the wrong hands, it could prove... troublesome. I need someone to take this ring to Mount Doom, where it can be destroyed."
I stuck some more weed in my pipe, and said, "Look, doll, let's get one thing straight- you can't come into my hole, tell me a fairy-tale about a magic ring, bat those pretty eyelids, and have me fall at your feet. I stick my neck out for nobody."
"But I saw Professor Sauron with that Balrog, he was talking about removing those prying eyes"
"Yes, Sauron was one of the first suspect something about Smeagol, it was all those potions full of rotten fish that gave it away he said. He knew he couldn't tackle Smeagol alone so he enlisted the help of Saruman. He was the one who found you unconcious"
"You mean... Sauron is innocent?" stammered Frodo
"Yes you fool of a Took! I've been trying to tell you that for the last 4 years" snapped Gandalf rather angrily "Now get some rest so we can send you home to your awful Uncle Bilbo"
