Friendly Greeting is the 33rd cutscene in Run 3, if counting all those hidden and optional cutscenes.
After reaching The Meddler on the Angel Missions checklist, the Angel meets the Pastafarian on Level 47 and suggests that the Pastafarian misses her 'weird cult' and asks her to follow him, so that they can go home together. The Pastafarian accepts the offer.
The Pastafarian then reveals that she accepts the offer so that she can "teach him politeness". Despite that, he ignores her entirely, saying that he is only rude to people "who deserve it" and calls the way she runs stupid as an example.
