is high strung. He is picky and controlling with his kids but loving as well because he cares so much. He uses quips to ward off his anxiety.

That's a recipe for high blood pressure, the focal point of the sixth episode of season two of "Chrisley Knows Best."

"Who would imagine I would have high blood pressure?" he says.

Part of the problem: He doesn't exercise and loves fried food. He isn't even always hydrated because "I hate water."  The doctor says the remedy is simple: better diet, more exercise.

"You've been a ray of sunshine," Todd says sourly.

This sounds like a standard-issue sitcom plot line. You know Todd will try to change but not really.

One aggravating high blood pressure inducing incident that they clearly could not make up: his youngest daughter Savannah wrecking her car yet again. She ran off the road. Todd rages. She's a terrible driver. On the bright side, there was nobody else involved.

So her driving privileges are revoked. The damage to the car? $15,000.

He tries to take yoga. He doesn't enjoy it. He tries jogging. He doesn't like it. He switches to power walking.

His solution to relax him? She gets a bike instead.  And he asks his kids not to sit on the furniture, which feeds his "zen."

Here are the best lines:

- "When that left eye starts twitching, you better run cos he's crazy as hell," Julie, about her husband Todd.

- "I don't know how somebody could get so stressed out when they get their way every day." - Chase about Todd.

- "Another stress reliever: sex." - Chase, trying to be helpful.

"Grayson, get away from that one cos stupid is contagious." - Todd, quipping to reduce a sensitive topic.

- "Julie, I need you to hit 9-1 because it's only going to take a second for you to hit the other 1 before I flip my ****." - Chrisley

- "I don't really need to run. Only other time I was running was leaving my first wife." - Todd
