An example of a pun is ‘a bicycle can’t stand on its own because it’s two-tired,’ a joke that makes me groan every time I hear it.

My friend asked me to tell a pun, so I said ‘I was trying to figure out how lightning works when it struck me.’

A pun can be extremely corny, but some are very clever, such as ‘Santa’s helpers are known as subordinate Clauses.’

Most people consider any joke that employs word play to be a pun, though a real pun is not quite that simple.

My friend is a photographer whose favorite pun is ‘she had a photographic memory but never developed it.’
