Teacher with a poor memory

A head teacher had a very poor memory for names and could not even remember the names of his own staff.

He had what he thought was a very clever way of covering up this defect.

"Let me see," he would say. "How do you spell your name?"

Sometimes this worked, but it failed dismally with the Welsh science master who craftily suggested he write it down carefully.

The headmaster took out his pencil and notebook and the science master then slowly and carefully articulated the letters J - O - N - E - S.
