When I was younger and very naive, an unscrupulous Real Estate agent persuaded me to make an offer on a "modular home". The offer was contingent on particular financing which, as it turned out, excluded mobile homes. I went to the home to try to renegotiate and she declined to accompany me but she sent the sellers agent to ambush me.
The poor aged seller was on his last legs with emphysema and his agent got him so worked up with the notion that I was trying to screw him over that he stood up at the table screaming in fury at me until he suddenly passed out cold right there on the table. I thought he was dead.
As soon as his wife confirmed that he was not dead, "he just does that when he gets excited", I got out of there and fired that agent. Over a year later they fired their agent.
Anyway, your comment made me think of that scene.
WOW..... it can happen.
