The old man and the pot

There once was an old man who had too many trees. He had them in pots, so all was not lost, but he had dug two pots into the ground. He said because they were falling over. That would indicate that the pots were too small for the type of tree. Anyway, he was asked to remove the trees and he said he would. He didn't, so he got a letter. The letter gave im 14 days. He then stormed about and asked if the chair's signature had been forged. It hadn't. He then stropped off and a few days later removed from the ground one of the trees in pots. There was a huge hole in the side of the pot where the roots were coming out.
