If they ever do "Family Feud: Thunderdome Edition", sign these guys up . . .
A guy in Bristol, Tennessee was mowing the lawn recently when his 76-year-old father came after him with a CHAINSAW.
The dad's name is Douglas Ferguson. It's not clear what they were arguing about, or how things got to the point of CHAINSAW serious. But it was part of an ongoing feud.
And the son was forced to defend himself . . . by running his dad over with THE LAWNMOWER.
Douglas suffered serious injuries, and ended up losing one of his legs.
This all happened back in June, but cops didn't arrest Douglas until last week, because he was still recovering.
They charged him with attempted murder, and for violating his probation from a previous assault charge.
His son isn't facing any charges
