Johnson's predecessor refused to honour the outgoing prime minister as he exited the Commons, unlike her colleagues.
"This #PMQs is making me want to bang my head against a brick wall."
Johnson ignored pleas to keep the exchange civil by branding Starmer a “great pointless human bollard”.
And it wasn't just Labour MPs.
"We never know when our time is up," the PM once wrote as a backbencher.
“He always tries to blame other people for his mistakes," Gary Sambrook said.
"What next – King Herod with a Children in Need badge?"
Keir Starmer: "Pay rises for City bankers, pay cuts for district nurses - that’s the new approach"
The Labour leader said Boris Johnson was playing games like he was on Love Island.
The PM was likened to Monty Python’s black knight, called a "lame duck" and told his own party "loathed" him.
