The Ever Expanding Vocabulary of Jack

What guy doesn't like a red convertible?

Jack is a man with a lot on his mind.  He talks non-stop, constantly expressing himself verbally.  The catch is that not all of what Jack says is comprehendible.  In between the Jack-chatter, Jack has started to say a lot of distinguishable words.  Being just shy of his 18-month birthday, we decided to write down all of the words he currently says, so in a few years, when he really won't stop talking, we can look back and reminisce.   And the words are, in no particular order (except the first one, which was his first word):

1. Dada
2. Mama
3. Papou
4. hi
5. Baby
6. by-bye
7. duck
8. quack
9. box
10. socks
11. shoes
12. blocks
13. this
14. more
15. me (usually said when he wants something)
16. milk
17. up
18. cat
19. car
20. vroom
21. apple
22. Bone
23. ball
24. football
25. cheese
26. dog
27. Elmo
28. go
