Sick of being on the receiving end of her boyfriend's practical jokes, a Czech woman got her revenge in one of the most horrifically tortuous ways possible.
By spraying his toilet roll with pepper spray.
As you can see from the video, the effects were immediate, agonising and - for the girlfriend at least - hilarious.
Obviously here at the Huffington Post we can in no way endorse such behaviour no matter how hungry you are for revenge.
