From Will & Guy.
A little boy liked nothing better than to sit on his grandfather’s knee and have stories read to him. One day, after a story about Noah’s ark and how Noah led pairs of animals to the safety of the ark, the little boy asked, “Granddad, you are very old; were you in Noah’s ark?”
“Gosh, no”, said Granddad.
“In that case, why didn’t you drown when the flood came?”
