We're a long ways from February, but Big Bang outdid itself in the Romance Resonance department. It's a love it or hate it episode — me, well, it grew on me. Nothing went as planned, Sheldon made a mistake so big I'd be ashamed if I made it, Penny tries to get romantic, Bernadette tangled with infected racoons and missed her party, so the gang went to the hospital where she was quarantined.

From 7x06, the latest episode, Bernadette's Song is available online, with lyrics. The whole episode is on CBS.

If I Didn’t Have You (Bernadette’s Song) [MusiCares® Version]
If I didn’t have you
Life would be blue
I’d be Dr. Who without the Tardis
A candle without a wick
A Watson without a Crick
I’d be one of my outfits without a Dick-ie
I’d be cheese without the mac
Jobs without the Wozniak
I’d be solving exponential equations that use bases not
found on your calculator making it much harder to crack
I’d be an atom without a bomb
A dot without the com
And I’d probably still live with my mom

And he’d probably still live with his mom

Ever since I met you
You turned my world around
You supported all my dreams and all my hopes
You’re like Uranium 235 and I’m Uranium 238
Almost inseparable isotopes

I couldn’t have imagined
How good my life would get
From the moment that I met you, Bernadette

If I didn’t have you
Life would be dreary
I’d be string theory without any string
I’d be binary code without a one
A cathode-ray tube without an electron gun
I’d be “Firefly,” “Buffy” and “Avengers” without Joss Whedon
I’d speak a lot more Klingon Heghlu’meH QaQ jajvam

And he’d definitely still live with his mom

Ever since I met you
You turned my world around
You’re my best friend and my lover
We’re like changing electric and magnetic fields
You can’t have one without the other

I couldn’t have imagined
How good my life would get
From the moment that I met you, Bernadette

Oh, we couldn’t have imagined
How good our lives would get
From the moment that we met you, Bernadette
