[Verse 1: Simon Helberg, Jim Parsons, Mayim Bialik, Johnny Galecki, Kaley Cuoco, Kunal Nayyar]
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

[Bridge 1: Simon Helberg]
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

[Chorus: Simon Helberg]
I couldn't have imagined
How good my life would get
From the moment that I met you, Bernadette
[Verse 2: Simon Helberg, Jim Parsons, Mayim Bialik, Johnny Galecki, Kaley Cuoco, Kunal Nayyar]
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
Heghlum'meH QaQ jajvam
And he'd definitely still live with his mom

[Bridge 2: Simon Helberg]
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

[Chorus: Simon Helberg]
I couldn't have imagined
How good my life would get
From the moment that I met you, Bernadette

[Post-Chorus: All]
Oh, we couldn't have imagined
How good our lives would get
From the moment that we met you, Bernadette
