This my first palindromic limerick, and the only one I know of. It concerns the activities of someone whose job it is to spy on profanity such as tangoing and recordings thereof, and to report it in elaborate style without delay to a significant person who may assist in carrying out corporal punishment to the guilty party.
Tango-noter, a disc I peek at
In a temple: hot sin, a mad rat;
Ere we retard, a man
Is to help me tan;
I take epics, I dare, to no gnat.
If you know of any others, please let me know.
