"Dad, you got caught in the cookie jar," Amir tells his father. "You're trying to lose weight, I'm trying to help you." He then explains the ab stimulator works.

"It fakes doing sit-ups," Amir says, "so it's equivalent to 25 thousand sit-ups in one session. That belly will be gone, and I'm telling you, you'll have a six-pack."

As much as Amir wants to help his dad by introducing him to the stimulator, the TV arbitrator thinks otherwise, joking in a confessional, "I feel like I can better myself by reading the Bible and obeying what scripture says."

While Greg doesn't seem all that enthusiastic about using the ab stimulator, he joins Amir for a treatment. After their stomachs get all paddled up, the practitioner begins the treatment, and Greg's reaction is nothing short of hilarious. "Ah s--t!" he screams as Amir laughs by his side.

With the machine only set at 10 percent, Greg has a long (and painful) way to go. "This s--t feel like the electric chair," he shouts. "I ain't killed nobody."

Greg's reactions only get better as the machine's intensity level increases, so much so that Amir jokes that Nora, the judge's 5-year-old granddaughter, "could've taken that better than you."

The clip ends with one more funny quip from Greg as the machine reaches 100 percent capacity, saying, "I'm being electrocuted."
