Paddy, carrying a big bunch of flowers, rings his new girlfriend's door bell on Valentine's Day.
She opens the door, sees the beautiful flowers, and drags Paddy in and pushes him on the couch.
She lies back next to him, pulls her skirt up, rips her knickers off and says lustfully, whilst pointing down,"This is for the flowers, My Love!!"
'Don't be silly,' says Paddy, 'You must have a vase somewhere!'
