I visited a site this week that had just constructed its first "green" building, which is to say: eco-friendly. There were lots of interesting factoids about the building from the "green" carpet glue (which didn't work), to the flywheel driven UPS devices in the data center, to the heat reclamation design.
What I found most hilarious was the "green" bathrooms. They actually have signs over the toilets instructing you to pull up for #1 (liquids) and down for #2 (solid waste). In other words, in order to be green, it's up for yellow and down for brown.
Now if I just had a Crayola box, I'd have fit right in.
