I've got a few in my current fortress:
"The Stinky Fiend"
"Engraved on the floor is an exceptionally designed image of a dwarf by Udib Ducimlogem"
"The lizard of pregnancies"
"Engraved on the wall in a image of a dwarf by Adil Libashtosed"
A couple of amusingly-named engravings relating to the founding of my fortress:
"The untrustworthy city"
"The Acrid Shack"
"The Gleeful Accident"
(An engraving of a Dwarf shooting a Goblin)
"The Virtuous Fangs"
(A dog killing a goblin)
"The Evil Zenith"
... The artwork relates to the election of the dwarf Imush Bridgecrawled to the position of Mayor.
"The Dabbler of Tentacles"
This is an engraving of Ngokang Twinkledhates withering away. The artwork relates to the killing of (the goblin) by a trap in Anviltime in the early winter of 206 during Ugotetosp, "The Dangerous Sieges".
"The perfection of peace"
Another engraving of a goblin withering away in a trap.
However, my engravers seem obsessed with the ascension of my original (and repeatedly re-elected) mayor, Kogan Cloisterrain. Judging my the names of some of the engravings, it seems there may be some controversy about the legitimacy of the elections, and the competance of the mayor...
"The calamitous pantomime"
"The grasping order"
"The vulgar inconvenience"
"The Squeezing Boredom"
"The Puppet of Style"
"The National Deference"
"The defective speakers"
"The dominant tribe"
"The blind corruption"
"The cult of treating"
"The town of bowels"
"The mysterious luxuries"
"The maze of starving"
"The crunch of axes"
"The terror of dunes"
"The defective doctrines"
Several engravings also related to the Kogan Cloisterrain himself:
"The Whirling delight"
"The permenant natures"
"The Larval Pearls" (Kogan himself)
"The church of homages"
There was also one titled "The Messianic" something, but I couldn't find it. But all in all, it seems that Mayor Kogan has created some sort of personality cult around himself, wormed his way into the position of mayor through a combination of bribery (the "mysterious luxuries") and threates of violence ("The crunch of axes"). However, he has been unable to stop people engraving satirical graffiti all over the walls and floor of the fortress.
Besides, Imush Bridgecrawled seems to have been a much worse mayor.
