For me, its hard to tell.
Fake-the way it started,the young cat was super hyper on the first vid but too clam on the 2nd link. Plus im from a small oil town, it had its boom in the late 70's and early 80's. Got some family members that are roughnecks and they dont look like those guys. Besides tank, they look too clean cut and pretty boyish. They would never wear wifebeaters out there. All long sleeve and hardhats.
Real-the hits and the snoring/breathing at the end.
