In ENGLISH CLASS

My English teacher is The Lord of Nerds.
He claims he knows a lot of words
that rhyme with no other.
"Try me", I muttered.
This heated exchange then occurred.

"Surely you can't rhyme 'elephant'."
"Professor", I touted, "the Hell I can't!"
"Nice try", he told me,
He gave me a 'C'.
At least it was better than 'pelican'.

"You won't even come close with 'month'."
"Oh yeth", I lisped, "I'm no dunth".
"Well, how about 'orange'?"
"Will you thettle for 'porridge'?
He anthered with groanth and thum grunth.
