Interesting idea, but I think I would get frustrated from having to dig all my pens and pencils out of my desktop.

It's a /great/ idea! Kind of like pets pimping. I rent a girlfriend by the hour, why shouldn't I rent a dog that way too? (tongue firmly in cheek)

In Indonesia it's called "sawo". You definitely don't want to eat it when it's still firm. GrinNTonic's got it right about the flavor when it's soft and ripe. It will taste and feel like a mealy...
