Dad replaces teenage daughter’s vodka with water, plan backfires

This British father thought he was outwitting his teenage (but hopefully over-18) daughter when he pulled this prank on her.

Suspecting his daughter had stolen his favourite biscuits, he went looking for them in her room where he discovered a bottle of vodka she was saving for her night out.

As revenge, he decided to replace the vodka with water. Because that's good parenting?
