Lighthouse keeper

A fishing boat had crashed onto the rocks in heavy seas and the lighthouse keeper was taken to court for negligence. His lawyer asked him “Did you carry out your duties on the night in question?”
The lighthouse keeper described his work, how the machinery flashed the light on and off and how he constantly watched the seas through his telescope. The jury was so impressed with his testimony that they found him not guilty.
Later, the lawyer congratulated him on being such a clear speaker.
“Thank you,” said the lighthouse keeper, “but I was worried for a while.”
“How come?” asked the lawyer.
“I was worried that someone was going to ask me if the light was working.”
