Reportedly, this is the world’s shortest poem, attributed to Ogden Nash (but under debate):
Ogden Nash did, however, pen these shortie-but-goodies:
I like mustard
Even on custard
The trouble with a kitten is THAT
Eventually it becomes a CAT.
This may have been at the heart of why I loved Ogden Nash so much as a child — everything was poetry, no matter how long or short, how serious or funny.
