[Dc/marvel] deadpool and joker meet and get to chatting. Do they become best friends or do they hate each other? If its the latter is the joker crazy enough to mentally break wade or vice versa?

I remember something like this being asked once. 

As it turns out DP's crazy but he's rationally crazy. He has a rhyme, rhythm, and a reason that you can usually understand if you try hard enough. This is why its possible for the heroes of his universe to work with him.

Joker has no such thing, so they instantly would have that grating line where Joker is just too unpredictable to be trusted.

On top of that and the biggest reason they probably *won't* get on well together. DP is adamantly against harming kids, while Joker has done it for a laugh. If DP knew about that little Jason Todd incident, or the thing with the babies, he'd literally rip Jokers head off and shove it up his butt.

Could either break either? No. Jokers too far gone from reality, and DPs not enough of a torturer. While DP has a super power that's pretty much ensuring he stays crazy, and Joker can't do anything about that.
