The walls of ancient tombs and dungeons aren't sacred when an adventuring party passes through. One hundred different instances of dungeon graffiti!
'Here Lies Big Benson - Didn't Bring His Ten Foot Pole And Paid The Price'
'For a good time teleport to sequence [SIGIL SEQUENCE]'
'Sneek Atak Heer' with an arrow pointing behind a rock.
'Kobold Pride' in draconic.
'Your Mother Is A Succubus'
'Here lies Tom - 'There's no way that door can be a mimic'.'
'Here may be found the last words of Joseph of Aramathia. He who is valiant and pure of spirit may find the holy grail in the Castle of Aaauuuggghhh... '
'Dwarves Suck' written 8 feet up a wall.
'Don't bother trying to grave rob. The corpses don't like visitors. Come to think of it, they don't like anything living at all'.
On the ceiling, 'Beware of Trappers'
On the floor, 'Beware of Piercers'
'Archmage Drachnar and his Meat-Shields were here'
On the side of the passage, 'Only the penitent man shall pass ...'
A map of the dungeon that at first glance seems correct, but either upon closer inspection or actually trying to use it flaws are revealed, secret doors marked where there isn't one, hallways/staircases connecting the wrong rooms, etc.
'I'll make yer skeleton exit yer meat', in Orcish.
'Do not open.' on a door (door opens to a small, empty closet). 'Can you not read?' on closet wall.
'Don't Dead, Open inside' written in the same manner as on the show. While there's probably undead on the other side, the more or less garentees the room hasnt been looted.
'You don't matter! Give up!' Placed on a pair of small signs outside of the dungeon. Left by a well intentioned, if a bit stupid, bard.
'Sorry about your wall!' Place this one near either some blood from a prior battle or a hole in the wall for added effect.
'Fuck you!' placed behind a false door with a booby trap rigged to the door. Maybe a explosive/grenade/fire trap or a rockfall trap.
'Sharg's wife is most beautiful,' in orcish script, next to a crude picture of a fang-mawed dog.
A crude drawing of a kobold 'in congress' with a dragon. It isn't clear from the context and art quality whether this is a good or bad thing for the kobold.
68 tally marks scratched with incredible neatness. The last one looks very fresh and is shorter than the others...
'2 to the left, 3 to the right and straight below' in the language of a subservient race to the main dungeon dwelling race.
'[Cheif's right hand lackeys name] is [impotent/illiterate/part-human/vegetarian/a bookworm/short-sighted/other dire embarrasing trait for one of their species or job] ' this is a horrible rumour around the dungeon which (s)he has worked hard to stamp out and is now largely forgotton or at least unspoken. It is also 100% true. Make sure you introduce them by name when the PCs meet them!
'Trouble reading this? Try Lothar's Lights for all your torch and lantern needs. Just a short ride from this dungeon.'
'That last bit of graffiti was written by a [setting appropriate expletive]ing liar'. On a successful spot check, evidence of dried blood can be seen on the floor below the graffiti.
Originally a crude carving of a penis, someone painted over it to turn it into a kitten. If the paint is removed, the original carved design remains.

In tiny lettering: 'If you can read this, it's already too late.'
'The Minotaur is not what he seems.'
'Secret door here.'
'Joreth - I've gone back for her. Meet me at the Frog and Jester in Pennyworth Lane.'

'The Great Necromage Vilicous and his coterie of foolishly moral companions were here'
'Treat the dungeon with courtesy, and it will do the same'
'Worm Path - Look both ways before crossing' chalked on the floor on both sides of a large, circular tunnel intersecting a hall.
'Mind the gaps' written in large letters before an otherwise empty stretch of hallway.
'If you are reading this, do NOT look behind you until you exit the room' scrawled in shaky letters on the back wall of a dead end room.
'Please step on me' carved onto the surface of random rocks and tiles on the dungeon floor. The words are seen multiple times throughout the dungeon's exploration, and seem to disappear when no one is looking. The words constantly reappear no matter what, but if stepped on, helpful and relevant graffiti is found before the next encounter, puzzle, or junction of pathways.
'Grall Stonebringer was here.'
A picture of a gelatinous cube eating a person.
A cartoonish picture of a dwarf running away from a rust monster.
Written in very tiny letters: 'If you can read this, you can't see the goblin sneaking up behind you.'
There is a short and narrow room; the long-rotted remains of a door hang off hinges at the entrance. Scrawled along one wall, in an ancient language the party must translate is '[Name of some long-dead king] gobbles donkey goobers'. The opposite wall is also marked, with '[Name of long-dead queen] does the nasty.' If the party succeeds on a perception check they realize they're standing in a toilet stall.
A scribbled map of the dungeon, with a big X in one room and directions to a treasure. But it's a trick; when the party stands at that spot they trigger a trap.
'Abandon hope all ye who enter here.'
'Artival. Waited 3 days for you. Ran out of supplies. Moving on to the next level (or whatever floor is the one below.'
