[DC] Is telling a joke to The Joker a good idea or a bad idea?

So the Joker's a killer with a funny side, what if I play along? What if I act like him too, or, try to make HIM laugh? Will he get offended if I try to "one-up" him? Or will he respect me and think of me as someone who also loves to have fun?

I guess it would heavily depend on if the joke itself was good or not, but, in general, would he like it?

*Any* interaction with the Joker is a bad idea. There is no way to improve your chances with him. He's a random-number generator. Chaos. The textbook definition of unpredictable. 

He might find the joke hilarious, and shoot you while he's laughing, or not. He might find the joke completely unfunny, and shoot you for telling it, or not. If you don't tell him a joke, he might shoot you for being someone who hates fun, or not. 

There's no telling what might set him off or placate him. Being anywhere in his vicinity is a crap-shoot.
