A Land Far Away

So I was playing some PnP on wednesday when our halfling scout started throwing jokes from the blue. Besides being the self proclaimed "world's tallest halfling" he seems to have a good sense of humor too.

How many adventurers does it take to change a light bulb in the Tomb of Horrors?
6 so far...

Why did the sorcerer get pulled over?
His license was evoked.

Anyone have any more?

I'm sorry, but those were terrible puns!

For general D&D humour though, I find that Motivational Posters work really well:

There used to be a site that had a collection of 'PnP Famous Last Words' but I don't know if it's still around.
