Larry the Cable Guy was on fine form when he stopped by 'Late Night With Jimmy Fallon' (Weeknights, 12:37AM ET on NBC).

He told Fallon that he almost didn't make it to the show because his grandmother had been involved in a tragic accident.

"[She] farted and set her Snuggie on fire." How horrific! But not to worry: Grannie's okay now. "She has a bad bladder and she peed herself out."

This led Larry and Fallon to ponder the unique appeal of the Snuggie, with Larry concluding that, "If you're too stupid to operate a blanket you deserve to be cold every now and then." We love the Snuggie, but concede that maybe he does have a point ...

Larry continued to rip on what he termed "the dumbest invention ever" as Fallon roared with laughter.
