Honestly the Vogons were only the third worst poets in the universe. If you can read awful human poetry like anything by Paula Nancy Millstone Jennings, they won't faze you.
In the original radio series, the name was Paul Neil Milne Johnstone… who was an actual schoolfriend, or at least was at school with, Douglas Adams. He didn't appreciate being name-checked in the Hitchhikers Guide to the Galaxy so it had to be changed. I believe that if you closely watch the fake video graphics in the BBC TV series, you can see some of Adams' best efforts to remember Johnstons actual "poetry" on screen.
