I think this has to be the most unrealistic sentence I've ever come across:
"My God, I've been disemboweled."
Really? Really? Because I'm pretty sure that if such a thing happened to me, there would be some big swear words involved. For example:
"Are these my motherfucking intestines?
Or: "What the fuck is this ropy, bloody shit all over the place?
"Holy shit!" Or "What the fuck stinks so bad?"
I came up with these just off the top of my head and I'm not an author. For shame, Dean Koontz. For shame.
