I had one for encyclopedic and endorse..I just had to work all weekend...

He will tell you who you should endorse.
He will tell you the myths of Old Norse.
He's encyclopedic,
and often comedic...
He claims to be trained in "the Force."

Moving on....

In the past I have often enjoyed
Rhyming word that others avoid.
I try not to be pompous-
It can be quite arduous,
But I can't seem to use polyploid!
