Strangely enough, this is all true.

I had heart bypass surgery. For recovery, they have you do an exercise program. So I go to the doctor and he asks if I have been exercising. I reply, "Yes. Religiously."

"How is it going?"

"Well, at first it was kind of tiring doing all that once a week..."

"Once a week?"

"Yeah, you know, religiously. Just like church. Every seven days."
