Siths and Giggles

I've been exploring a family of functions and noticed a pattern in the continuity of their highest-order derivatives. Here's a list of the pattern I noticed:

n: {0, 0, 1, 1, 2, 2, 3, 3, 4, 4, ...} (so I'm just getting pairs that keep increasing)

k: {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, ...}

These values are corresponding.

I'd like to make a sequence that generalizes this pattern, but can't think of any. Any ideas?

Recently I've had a growing interest in producing some art, but I'm not a real fan of doing it on paper, so I turned to using MS Paint. If you have Windows 7 and its version of Paint, you might know how frustrating it is.

Anyway, I've been looking around for a pen tablet online, but I have no experience with picking out the right thing. I'd prefer one that doesn't have a touch capability for under $100. So far I've looked at the Wacom Bamboo Pen, but wasn't pleased with its area. Any advice?

What is the significance of rabbits and why are they supposed to be sexually attractive to men?

I'm referring to the ones you see in the Playboy Mansion and strip clubs.
