Cover-Up
[Black Hat looking slightly up is holding two rags stained red with blood while Danish is holding an equally bloody mop.] Black Hat: Okay, got the blood off the walls. Danish: I finished the floor.
[Black Hat drops the bloody rags behind him while looking up at the ceiling, Danish has put the bloody mop behind her leaning against the wall while covering her mouth with her hands.] Black Hat: Good; he'll be home any- Black Hat: Oh crap! We forgot to clean the ceiling!
[Black Hat has moved away from the bloody rags towards Danish who has taken her hands down. They look straight at each other. The bloody mop has fallen over on the floor.] Danish: There's no time! Black Hat: Wait, I'll handle it.
[Cueball with briefcase enters the house through the front door behind him, still standing open. He is greeted by Black Hat holding out a hand towards him. The corner of the room and the wall behind them and past the door is outlines with three lines connecting in the corner.] Black Hat: Hi. Did you know "gullible" is written on your ceiling? Cueball: Hah. Yeah, right.

Black Hat and Danish are trying to clean up the mess that some bloody murder most likely performed by them has left.  This story may thus be a continuation of 515: No One Must Know .
Another guy, Cueball , is on his way home and is about to arrive just when they are finishing the clean up. But then Black Hat realizes that the ceiling has also been stained (by the violent murder...) And now they do not have time to fix it.
But Black Hat knows how to deal with the situation, and when Cueball comes home, he says: "Did you know 'gullible' is written on your ceiling?"
Gullible means easily deceived or naive. This is a game many people play with each other "Whoa, someone wrote 'gullible' in the sky!" "Did you know when you look at the Microsoft logo upside-down it looks like the word 'gullible'?" Those that are gullible, check. Those that aren't, don't. [ citation needed ] In fact they will pointedly not do the thing that the first person has suggested as a show of how non-gullible they are. Black Hat uses this to his advantage to cover up the copious bloodstains on the ceiling and as expected Cueball just says "Hah. Yeah, right" and refuses to even glance at the ceiling.
The title text is hinting that Black Hat has had to cover up killing people several times as this trick has saved him many times. Of course there could also be other things than blood that he had to hide (the money he just stole etc.)
