Rank Idiocy
My mum was an English teacher, and was marking a pupil's coursework, when she read something along the lines of "Lady Macbeth washed her hands to try and get rid of her guilt which we will discuss further in chapter 3". I doubt the boy passed.

I also have a mate who is, shall we say, famous for being a bit gullible. I once said to him "In the next series of 24 the series will be 25 hours long because Jack Bauer's watch breaks and he has to go to H Samuels to get it fixed and it takes about an hour". I could've strung it out for ages, but I was so shocked when he actually believed me I just laughed.

He also stopped everyone during a kickabout in the park, pointed up and shouted "Hey everyone, look, its a spaceship!". When we looked it was a jumbo jet. His explanation - "Well it was going upwards!"

Thought of another one, I was working in Quasar (the laser gun place) explaining how to play the game to the kids etc, and I got asked about four times in one summer "How do you fire the gun?"
