Sometimes when I'm writing a strip, I think, 'It's been a while since I've used this character.  I better work him back in before he's forgotten'.

The result of doing such usually results in a joke that's so-so and seems forced, like the one you see here.  So, this one ended up being Ninja Rob's last appearance.

Now, had I made him a pirate, we'd probably all be wearing Pirate Rob t-shirts sporting references to downloading music and films illegally.

...Damnit!
