A man came into town on a Friday and stayed for three days and left on a Friday.
How did he do that.

This is driving me mad as someone asked me over a week ago and I still don't know and he wound't tellme the ansewer does anyone know the ansewer I would be most pleased.
Many thanks

Hint - You are thinking of "friday" as a day of the week. Expand your thinking, for example, "Friday" might be the name for his horse or car.

donf is right.

The horse's name is Friday.
