Your first pipe. The one you first looked at and said, "I want to light a fire inside that and stick it in my mouth".
Maybe it's the one you inherited from your dad, or even the cob you grabbed after all the Brown Leafers told you to start there.
Plenty of you guys (myself included) may no longer be in possession of that very first pipe, so let's go with the pipe you've had the longest.
As always, pics encouraged.
