The broadcaster has contacted the PM to apologise, and promised to not show the tweet in any repeats of Q&A.
"Q&A has apologised to the Prime Minister, Tony Abbott, this morning," a spokesperson said.
"This particular tweet should not have been published and the ABC regrets any offence caused."
ABC managing director Mark Scott sent the PM a text to apologise last night, but Tony Abbott told reporters that he'd been too busy to respond.
In the wake of the Zaky Mallah scandal, things had just started returning to normal at Q&A. The government was even letting its ministers back on the show. Nationally adored columnist Annabel Crabb was on the panel...
...And they were showing witty and insightful tweets on screen from viewers watching at home.
People could hardly believe what they just saw.
DID OUR EYES DECEIVE US?
Nobody could agree on how to feel about it. It was either the best thing ever...
...Or the worst.
Liberal MP Fiona Scott was the first politician to react, calling it "disgraceful", and tweeted a helpful screenshot of the offending tweet just in case anyone missed it.
Nobody could figure out how the ABC let this happen, or if they had given up and were just being massive trolls.
And just when it couldn't get any better/worse, Zaky Mallah weighed in!
And now, this is happening.
We'll let @AbbottLovesAnal have the final word with this oddly prescient tweet from last week:
