My Italian Wife does OB/GYN ultrasound, and a routine procedure is amniocentesis, where the M.D. inserts an ultrasound-guided Frankenstein-ish needle into the mom-to-be's belly to extract fluid for lab analysis....often, the Father-in-waiting wants to be there, comforting the mom. At the angle she's at on the table, she can't see *****, but the guy has front-row seats. All bets are off when the M.D. exposes the tray, and the instruments/needle are exposed. While most guys can handle it, some get the full white-eye roll-back and collapse on the floor when the VERY long needle is uncovered.
One time, she tells me, an burly Atlanta Falcons player fainted and hit the wall so hard the drywall covered his face in powder. The M.D. paused, and asked my wife, "Is he still breathing?" She noted the dust around his nose moving and nodded. "Leave 'em. Let's get this done."
I realized then why she keeps some smelling salts taped to the side of her ultrasound machine.
