Wiper gag is an article in Resident Evil Recollections. It was uploaded on 2 June 2016.
There's a certain scene in Leon's campaign in Resident Evil 6 that had me laughing at an entirely inappropriate time.
Leon and Helena are escaping from the campus after it has transformed into a living hell following the bioterror attack, when they miraculously come by an empty police car.
As Leon desperately searches for the key, if you make a certain action the wipers will start moving which prompts Leon to blurt out "At least the windscreen wipers work".
Also I know can't be the only person who thought of Resident Evil 2's intro when Leon searches the police car glove compartment...
