I just realized that "Bad Romance" is the new "Psycho Killer" in that it makes you sound like a crazy person if you ever try sing it a cappella:
Exhibit A: Chorus of "Psycho Killer" by The Talking Heads
Qu'est-ce que c'est?
fa fa fa fa fa fa fa fa fa fa better
Run run run run run run run away
OH OH OH
AY AY AY AY AY
Exhibit B: Chorus of "Bad Romance" by Lady Gaga
Caught in a bad romance
Ga-ga Oh la-la
Want your bad romance
Not to mention that "Bad Romance" also includes unexplained French lyrics ("je veux ton amour/et je veux ta revenge") and a reference to "Psycho" (as part of a trilogy of hilarious, misplaced Hitchcock references - "want you in my Rear Window" just became my favorite pick up line of all time).
In conclusion, if you are staying at your crazy, religious, paranoid aunt's house and she has never heard of that Lady Goo Goo or those Talking Faces, maybe you should refrain from singing either of these pop gems in the shower...lest you find yourself being exorcised. Of course, you also might find yourself the proud new owner of a Lithium prescription, in which case, I want your love. And I want your revenge.
