StarWars.com blogger Neil Baker made a Star Wars Alphabet for fellow Star Wars bloggers to put on Star Wars t-shirts to wear to the Celebration IV Star Wars anniversary commemoration a few months back.
Then he turned his alphabet Yoda into a DIY Yoda plush doll for a friend's kid's first birthday.
See the whole howto on his own blog, Oil Bath Bubbles, then you can figure out how to make your own Han and Greedo dolls. Then you and the kid can settle this thing once and for all.
