What is your favorite bait or lure to use and what kind of fish do you go after with them?

Generally I am a natural bait fisherman and prefer natural bait. There are times when I have to use lures such as crawdads, fly type lures for Trout and Salmon, and plastic worms for bass for example. The ones I mention here are lures I have had some success with. What is your favorite lure or bait?
