TWO stars of The Big Bang Theory have hurled personal insults at each other during a heated rap battle.
Kunal Nayyar (who plays Raj) and Mayim Bialik (who plays Amy) didn't hold back during their appearance on Drop the Mic, a comic battle rap competition series based on the popular segment from The Late Late Show With James Corden.
Nayyar picked on Bialik for her starring role on '90s TV show Blossom and also called her a nerd for having a PhD in neuroscience.
Bialik on the other hand mostly mocked her British-Indian co-star's heritage.
Here are some of the best insults from Nayyar:
It's my pal Mayim, isn't that awesome
She's a former child star who never quite blossomed.
She left TV for a PhD. I swear,
She came back to act, nobody cared.
Yes you were on a show where Joey Lawrence said 'whoa!'
You walk into a room and everybody's like 'no!'
Maybe change your name, your name sounds awful
Mayim Bialik? Is that a side dish for falafel?
You have a PhD so answer me this, honey
You can deconstruct an element, why can't you be funny?
And here are some of the best insults from Bialik:
He loves golf, let me give you this hook
Your wife's Miss India, I'm sure she likes you for your looks
You're not the Big Bang rapper, that's a reach
Come to think of it you're basically our show's Screech
You got balls making fun of my name on purpose
'Cos you got the kind of name that makes Donald Trump nervous.
