Tony Abbott motions for Julia Gillard to have Peter Slipper resign over misogynist conduct. Gillard not only opposes it, but then lays into Abbott for a good 15 minutes, outlining instances where he conducted himself in a similar manner.
Kevin Rudd destroying Julia Gillard's political career three years after she stabbed him in the back.
Malcom Turnbull also returning the favour to Tony Abbott in a decisive, swift contest, destroying his political career and taking the office of Prime Minister after Abbott only held power for literally a few days less than a mere two years (meaning he was on the top job for less time than Rudd or Gillard by more than a year), after the latter took the leadership of the Coalition from Turnbull.
Even better is the fact that, with regards to retirement pensions for ministers and members of parliament, to be eligible for a full Prime Minister's pension one must hold the position for two exact years, meaning that Abbott won't be able to receive a full prime ministerial pension once he retires, assuming he doesn't make a return to power in future.
