LEDs without the use of current limiting resistors

Hippynerd:
Where do you get resistors for less than one cent each? I get them cheap on the internet, and they are 2-5 cents each, in packs of 100 or more.

Pretty much anywhere. Here's some 10K resistors from DigiKey for 0.2 cents each at qty 100:

As an aside, this is easily my favorite thread of the new year.

Those are 1/16w 0402 smt parts, I actually have some of those, have you ever tried soldering them?

I should look over digikey and mouser more often, but I find them those sites a bit overwhelming.
