Why does Capulet think the following exchange is so funny?Capulet. Make haste, make haste. Sirrah, fetch drier logs:
Call Peter, he will show thee where they are.
Sec. Serv. I have a head, sir, that will find out logs,
And never trouble Peter for the matter.

He knows that Peter is not that smart.

The servant is calling himself a loggerhead.

Right after this exchange, the servant trips over a log.

He knows that the servant has no idea where the logs are.
