Valentine's gift

[rebbonk]

Roger, who was 19 years old, was buying an expensive bracelet to surprise his girlfriend on Valentine's Day from a very smart jeweller's shop in Hatton Garden, London.

The jeweller inquired, 'Would you like your girlfriend's name engraved on it?'

Roger thought for a moment, grinned, then answered, 'No, instead engrave "To my one and only love".'

The jeweller smiled and said, 'Yes, sir; how very romantic of you.'

Roger retorted with a glint in his eye, 'Not exactly romantic, but very practical.
