Traditionally, after the limerick from Peru comes one with even fewer lines revealed:
There once was a man from Verdun,
Ekptl hkndekbmq eff oopqvodw ro gkhl uhr.
Ol onrh lts r fbel,
Gash ona hrm kh Odez,
Rmw bshobrodw onmp qpah lsa gzh.
Can you figure out what encryption method is being used on the second line (since I'm sure you've figured out by now what the plaintext is), and use that knowledge to figure out how this Verdunnian man's limerick went?
Note: each line is encrypted separately, and it's not a Vigenère cipher this time around.
The key is a writer of complete nonsense.
