Calling all stoner jellies - why do you need so many pipes?

Ok, I’ve noticed that lots of stoners will buy multiple pieces. They will have 6 pipes, and 7 bongs, 2 or 3 zongs, several cigas (sp?), a few blunts… The list goes on and on. Years after acquiring “the ultimate piece”, they will still stop by the headshop to pick up a new one “because they have the money”. And yet, they never say anything bad about a piece so long as it’s not a makeshift pop-can. It’s never like “Well, the last one I bought was really crap, but it fit my price range, so now I want to upgrade”. After they’ve gotten a quality pipe, bong, zong, blunt, and ciga, what else do they need?

What’s going on here? Why do stoner’s do this? Is it a collector’s thing? A culture thing? What??

If anyone doesn’t feel comfortable answering this question so openly, feel free to pm me the answer privately – I’m dying to know.
