My sister’s friend is the daughter of a former professor of mathematics who is also a well-known writer of joke books. An unusual combination but why not?
My sister was at her friend’s parents house over Christmas and told the author a joke she had heard. He said that in his line of work he hears a lot of jokes and most of them aren’t new and the ones that are new aren’t funny but that this one was both new and funny. Here it is and I’m sorry if you’ve heard it before.
I am the Ghost of Christmas Future Perfect Subjunctive, I am here to tell you what would have happened were you not to have changed your ways.
Apparently in their house, the Wise Men travel to the crib from across the room as is the case in many other houses. I’m pretty sure though that it’s only in the retired maths professor’s house that the distance is measured for every day so that travelling at a constant speed they arrive in the crib on January 6.
