The spouse had his physical, and managed to stump two doctors and five nurses.
Nurse #1 took his BP. "That's not possible."
Nurse #2 (looks in.) "What's not possible?" (Goes and gets her blood pressure cuff). "What the hell..?"
Dr. S comes in, gets fresh blood pressure cuff from drawer, removes protective plastic, and takes his BP. "That's not possible!"
Dr. S sent him over to Cardiology, where Nurses #3-5, AND the cardiologist took his BP, with the same results and same comments. His BP was 165/20; 165/0.
Cardiology put him an a 24-hour heart monitor. The man decided to go deer hunting the next morning, and while he didn't get a deer, the neighbor he went with asked about every ten steps, 'Are you all right? Doing ok?'
(Spouse seriously considered shooting the neighbor at this point!)
He went back the next day, and the cardiologist scheduled him for a heart cath the next month.
It was a few days later the spouse revealed he'd hit a 9,000 volt power line with the excavator he'd run back in September.
