A touch of humour

After today's effort, doing the new grammar transformation exercise, a touch of humour to ease tension:

A man stops another man in the street and says to him:
"How you've changed, Henry! You used to have fair hair and now you're bald. You used to be fat and now you're thin."
"But I'm not Henry."
"Oh, So you've changed your name as well!"
