Rigor Mortis Erection
I love this movie.
But there are a few plot holes, most of them are overlooked because they are part of the comedy. Including this one:
Bernie is fucked by his girlfriend. The boys are as surprised as we are, and they comment on it saying something like "she doesn't look like someone that wouldn't know".
Hence, she managed to fuck him so he must have had an erection.
That could be explained by rigor mortis, so that his dick was hard or got hard when he died.
My problem with this plot hole is: wouldn't his erection be visible, and be a social problem, in most other situations? If it's hard when she fucks him, it's been hard since he died and it will stay hard as long as he's dead. Bernie is mostly sitting, but even then it should be noticeable. Certainly he should be pitching a tent when the boys make him stand up.
How come it's not noticeable and nobody takes note of it?
The only possible explanation is that Bernie's dick is very short, so his girlfriend is fine with it (as it's hard and she knows already it's very short), but everybody else doesn't really see it through his clothes.
How do you explain this conundrum?
