Go on, give her the Frasier DVD box set. Then order yourself the Frasier 'Blu-Ray' Dvd Boxset. Then when it arrives, brag about how you have the high definition Blu Ray edition and she has the sucky normal version.
Even though she won't know what Blu Ray means, she will be driven mad with jealousy that you own something that she can't have / comprehend.
To add the final nail in the coffin, tell her that the Blu Ray edition has special features and interviews not found on the inferior normal DVD edition. When she asks to see them, say no.
A nice finishing touch would be to storm out of the room clutching your precious Blu Ray boxset whilst kicking the toy Eddie against a wall, then look back at her and say 'What's with you and the f**king stuffed animals, what are you? Five years old?!'
By the way girls, I'm currently single at the moment (for some weird reason), who fancies a bunk up?
