Over dinner Nik kept trying out new jokes on me:
What does a cow do when it's in danger? He digs a hole and goes to another farm.
What does an owl do when it's in danger? He finds his escape spoon.
After quite a number of these I asked Nik why he was making up all these jokes. He said, "Because my old ones don't work."
I didn't have the heart to tell him that I don't think these new ones will work any better...
