Is Dennis Quaid Really Freaking Out In This Video? (Video)

Earlier this Tuesday morning on The Free Beer & Hot Wings Morning Show they played a clip of actor Dennis Quaid freaking out and storming off the set of his latest film. However, this video may be a Jimmy Kimmel skit...but is it? Or are the Quaids crazy? 

I don't know if this is fake or not, but this video kind of brings into question the mentality of the Quaid family.
