"Who Pushed P.R.?" is a storyline from the Australian television soap opera Neighbours, which began on 23 August 2010 with a special week of episodes. The week culminated in the soap's 6000th episode (broadcast on 27 August), where the character Paul Robinson (Stefan Dennis) is pushed from the Lassiter's Hotel mezzanine by an unseen assailant. The storyline aired as part of the show's 25th anniversary and Dennis's character was made the focus of the storyline as he was the only remaining member of the original cast. The storyline was initially going to see Paul being shot, but the show's G rating prevented the production team from going ahead with it. Events leading up to and following the attempted murder put several characters in the frame, in the style of a whodunit mystery.
Dennis was one of two cast members who knew the identity of the culprit; he was told minutes before he filmed the scene in which Paul was pushed. The rest of the cast found out a couple of weeks after the 6000th episode was broadcast. The person responsible for the attempted murder was revealed to be Rebecca Robinson (Jane Hall) during the episode broadcast on 27 September 2010. Hall revealed that she had known her character was responsible from the beginning. The "Who Pushed P.R.?" storyline was well received by critics and viewers. Despite low ratings for the 6000th episode in Australia, the storyline provided the show with a small ratings increase in the UK.
