Melissa McCarthy decided that what the world needed from her guest host gig on 'Jimmy Kimmel Live' was a lesson in fake news and science but she wasn't on the side of the fence you'd think she's on.

Thankfully, Jennifer Aniston was also on hand to add some reason to the "debate", but we use the word "debate" loosely as McCarthy proceeded to wrestle with Aniston once she started to offer any sensible information. And then things just went completely off the rails.

What we will say is that we are fully ready for the McCarthy/Aniston buddy cop/chef/spy/whatever movie.
