Go to the shop and buy 7" singles with neat sleeves. That's what I do.
Recent winner is an old, beat-up 45 by the Daddy-O's (no sleeve; name loophole). Swank! Pleasant, with an even better name but not quite as good: the Five Blobs. Neither measures up to my favorite beat-up 60's novelty 45: the Phantom 5 doing "Graveyard". And even that pales next to the most ludicrous novelty single of which I know, Alan Copeland's 1968 beauty, "Mission: Impossible Theme Norwegian Wood".
So good, it won a Grammy (for Best Contemporary Pop Performance by a Chorus).
