Kane ain't the only famous person running for mayor in Knox County -- the WWE star's opponent has a serious Hollywood background ... and even played a key part in "Friday Night Lights."
Kane (real name Glenn Jacobs) is running against Bob Thomas -- who played the sports radio host Slammin' Sammy in the FNL movie. He was the first and last person you hear in the flick and his voice was a key part in moving the story along.
He's also a real-life radio DJ who had a big show in Knoxville for 25 years.
