It depends on whether you're dealing with one of the curved Peterson System pipes or one of the other models. It it's really stuck, you can try dripping a little mineral oil around where the stem enters the shank and then apply regular, gentle pressure in a rocking motion. It mat also help to refrigerate the pipe for a while before you try this. Good luck!
The stem is the part of the pipe that connects the bowl with the mouthpiece of the pipe. If there is no mouthpiece, the smoker will bite down on the stem itself.
