Ninja's first appearance was here. Stay tuned for the epic confrontation that will be even more action packed than Vik's battle with the toaster.
And speaking of the toaster...
Its RAM chip was never destroyed!!
Duh Duh DUH!
(Those "duhs" were actually the flute motif from the Austin Powers theme song, not the dramatic cliffhanger music. It's easy to get them mixed up like that).
