Fun with punctuation (yes, that's possible)

I was reading the National Education Association web site yesterday (partially for ideas, partially just for fun), and I came across these great sentence-punctuating activities for students (or all of us). I'm still laughing.

Punctuate the following:
1. a clever dog knows its master
2. i saw a man eating lobster
3. the butler stood in the doorway and called the guests names
4. [a want ad] WANTED: piano to replace daughters lost in fire
5. [a newspaper headline] father to be stabbed to death in street
6. [a book dedication] to my parents the pope and mother teresa

Answers:
1. A clever dog knows its master. NOT: A clever dog knows it's master. (Read: Barley)
2. I saw a man eating lobster. NOT: I saw a man-eating lobster.
3. The butler stood in the doorway and called the guests' names. NOT: The butler stood in the doorway and called the guests names.
4. WANTED: piano to replace daughter's lost in fire. NOT: WANTED: piano to replace daughters lost in fire.
5. Father-to-be stabbed to death in street. NOT: Father to be stabbed to death in street.
6. To my parents, the Pope, and Mother Teresa. NOT: To my parents, the Pope and Mother Teresa.

Of course, I'd be remiss if I didn't also mention my personal favorite, which the NEA seems to have overlooked:

Punctuate:
a woman without her man is nothing

Answer:
A woman: without her, man is nothing. NOT: A woman, without her man, is nothing.
