Why do some zits squeeze easily, while others have to be dug out with fingernails?

Answer:
I wouldn't suggest you "dig" out your zits.. sounds like it could leave some nasty scars.
Now to answer your question, all zits are not alike. The pore that is more easy to squeeze has its bacteria, oil, dirt that is clogging it very near the surface. However, other zits have their bacteria deeper within your skin. So don't even try popping those. You will end up bleeding and possibly scarring yourself.
Heres a tip to make popping easier (although I personally don't recommend popping your pimples unless it is absolutely necessary)-- take a washcloth and soak it in warm to hot water (not to hot!). Squeeze out the excess water and gently lay it on top of your face. Let the steam sink into your pores-- this will open them as well as pull the pus from the pimples outward. Doing so will make popping your pimples much easier.
