The pun is mightier than the sword!
CW: mild off-color humor, and a long way to go for bad puns.
A beech tree and a birch tree were living in a forest. A sapling started growing between them.
The beech tree said, "Look at my son. Isn't he a fine looking tree?"
The birch replied, "Your son? That handsome sapling is obviously my son."
The two trees argued until a woodpecker flew by. The beech called out, "Hey, woodpecker! Could you settle an argument for us?“
"Sure. What do you need?"
"Can you prove to that ignorant birch tree that the good looking tree growing between us is obviously my son? It's way too good looking to be a scraggly birch!"
"Oh, no," said the birch. "It's way too noble a tree to ever be a beech."
The woodpecker agreed and flew down to the young tree, whacked it with his bill a few times, and said, "I hate to disappoint you both, but this is neither a son of a beech not a son of a birch. It is the finest piece of ash I've ever put my pecker in!"
