i just know mulder's downstairs neighbors HATE him for bouncing that basketball all over the place not to mention all the bumps and knocks every time someone tries to kill him in his apartment
every time he leaves on assignment or runs off after aliens for weeks at a time they think thank GOD he moved out until they hear the basketball again at 2am signaling that hes back
i think there's a non-zero chance that at some point around seasons 1-3 scully fell asleep on the couch watching a history channel documentary about world war ii naval battles only to wake up at 2am to the sound of mulder's voice, panic thinking he broke into her apartment, and then realize he's a guest talking head on some proto-ancient aliens show. and then she mocks him mercilessly about it the next day at work.
