I asked a question and didn’t get an answer. Do you know?

There must be a knight wearing knickers in a tomb. Surely that must be wrong, so I asked the whale, he was very honest, he answered half my question, then knocked me over with a splash of his tail. Shall I wait untill Christmas? No, I’ll ask the folk with the lambs. and the wriggling swords.  They were useless, they pointed me in the direction of the gnomes, who waited in the garden, Fishing by the pond, whispered the answer in my ear.

The answer was silent but what was the question?
