"If u want to buy a Â£97 shirt and u borrow Â£50 off ur mum and Â£50 off ur dad.. So u got Â£100. U buy the shirt and uve Â£3 left over. U keep Â£1 urself and u give ur mum and dad a Â£1 each. So u now owe them Â£49 each which is Â£98 altogether.. U put ur pound back in and u get Â£99. Whered the other Â£1 go?" It confused the fuck out of everyone, even took me a minute to understand.
