Bringin' on the Heartbreak

DG and I were sitting at our computers tonight each doing work and out of the blue, I started singing, "You're bringing on the heartbreak, bringing on the heartache, You're bringing on the heartbreak, can't you see? You've got the best of me, ooooh can't you see?" Honestly, I don't know any more of the lyrics and it was painful as I tried to hit the high notes. Next thing I know, DG has this Def Leppard song blaring out of his speakers.

Me: (confused)Is that the song I was just singing?
DG: Yes!
Me: Where did I get it from? (disturbed) Were you singing it?
DG: No
Me: What made me sing that awful song?
DG: (pointing to my belly) You ARE carrying my baby, you've got 80's metal rock inside of you.

For the love of all things nooooooooooooo.
