True story....
A lady I know has a downs syndrome boy (he's 30 and big as an ox) anyhow she works and every hour she rings him to make sure he is OK.
Last week she rang him and he told her everything was good and he had caught a Troll!
Unfaised by this she said "good on you" and went back to work.
Next hour she rang he again said all was good but the Troll had tried to kick him.
Again she was satisfied and went back to work.
Hour later she rings again, this time he tells her the Troll was being very noisy so he locked him in a cupboard!
Now a little bit worried she drove home, outside her house she could hear loud noises from inside so being a cautious woman she rang the Police.
When the police arrived they found the son braced against a cupboard door and a very annoyed and upset Dwarf trying to get out.
The woman had been reading fairy stories to the boy recently and never having seen a Dwarf, when one just happened to walk past the gate he rushed out and grabbed him up, ran back inside and imprisoned him.
