If I didn't have you, life would be blue, I'd be Doctor Who without the TARDIS,
A candle without a wick, a Watson without a Crick, I'd be one of my outfits without a dickie,
I'd be cheese without the mac, Jobs without the Wozniak,
I'd be exponential equations that use bases not found on your calculator that make 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.
(chorus) And he's 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, cathode tube ray tube without an electron gun.
I'd be Firefly, Buffy and The Avengers without Joss Whedon.
I'd speak a lot more Klingon, "Heghlu'meH QaQ jajvam."
(chorus) 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.
(All together) Oh we couldn't have imagined, how good our lives would get,
from the moment that we met you Bernadette.
