His real name is Dan Whitney and he's not southern.
I've seen rare footage of the real guy behind the 'Larry the Cable Guy' character. He's a dude named Dan Whitney who spent his childhood in Nebraska and West Palm Beach Florida. He had a middle-class upbringing and his dad was actually principal of an elementary school in Florida. He doesn't have a southern accent and none of his 'cable guy' mannerisms are true to his own character.
You WILL respect my AUTHORITAAAAH !!!!
