What did stitch say at the beginning of lilo and stitch?

The solution would be like this for this specific problem:

6!

6 * 5 * 4 * 3 * 2 * 1 = 720 So, 6 basketball players can be listed in about 720 ways in order in a program.

If you will consider growling and snarling as something that stitch spoke, then yes, he growled and snarled at the beginning of lilo and stitch. But the first line that stitch uttered with words that are clear were " Hmm? Meega, nala kweesta!"
