OOD
Personally the tradition say that Christ did smile during one event in the NT. It was when he wrote in the sand and later spoke to the people who were abut to stone St Mary Magdalene. We dont know why he smiled. Personalyy I believe that God created humour, but that Satan tries to pervert humour and make it perverse. When a baby laugh, this is not a consequence of the fall from grace. I believe good laughter are from God and that Christ laughed for example at the wedding in Canan. He even transformed water to wine, even though the guests must have drunk a lot before this. A pharisee could accuse Him of passion towards wine. I think He wanted the poeple to have fun and perhaps even laugh some more.
