Sitting right next to me in the office is a (as yet, not too big) banana tree. It isn't exactly beautiful, poor wretched thing under the parisian climate, but it's green and of course that's the best colour anything can be.
However it appears to be exhibiting behaviour unknown as yet to me. If you aren't familiar with the way banana trees grow, it's fairly simple: new leaves start appearing at the top in furled cylinders, and slowly unfurl into an inverted cone and then into a large full-fledged leaf.
There is nothing peculiar with this banana tree's growth pattern. It's just that every time a leaf unrolls, it turns out to contain a pen. Not a special pen, your regular ball-pointed office furniture complete with the Clickety-Omatic fine tuned to perfectly annoy your cow-orkers during meetings. Most of them blue, of the "Paper Mate - Comfort Mate - M" brand (no, that's not a condom reference).
I'd think it were just one of my amusing coworkers from the research department doing it weren't it for one detail: the pens are always drained dry even though no one uses those because they're ugly.
I hope that by the time that tree grows larger, I'll have a chane to move to another office...
