When I was on the voluteer fire department, we got a call for a moose vs. car accident.
Little car, like a Ford Escort (hey, it was a while ago...) Nose of the car went under the moose, the moose rolled across the hood and ripped the roof plumb off it. The driver's side A pillar gutted that moose slick as could be and the entire interior, not to mention the driver, was covered in moose breakfast and most of it's innards.
She survived since the seat back broke and she was laid flat, but we had to caution her not to open her eyes or mouth until we had a chance to wipe her down with pretty much every bottle of saline we had on the rig.
I was on the scene of some pretty gruesome accidents, but that's as close as I ever came to barfing.
