Fr James Martin of America magazine is author of the best-selling book of religious humour titled Between Heaven and Mirth.
He has recorded a series of 40 jokes over the space of 40 days to remind readers (and viewers) that laughter is a gift from God.
He says humour is part of a healthy spiritual life.
Joy is, as legendary 20th century religious thinker Pierre Teilhard de Chardin said, the most infallible sign of the Holy Spirit.
