It's a fairly common pasttime (at least in my building!) to poke fun at the "Art" collection (more details on that collection here). In particular in our building, a bunch of us think that some of the "Art" is just silly, such as:
There are some really cool pieces too (my personal favorite is this artist who went to the MOMA and stood in front of several famous works, wearing clothing that made him blend in to the art - even to the point of replicating the shadow below the picture by tying a sash around his knees). But for the most part it's a source of entertainment for us.
A couple of years ago we did a funny video spoof about it, and as part of the spoof we put together fake art and hung it in our building representing the life of a PM and tester (with little cards next to the works explaining the mediums, of course). See if you can guess the discipline of the person who created these :-)

Ah yes, you're causing me to recall, with fondness, the art at Andersen. There was the one-armed girlscout (a statue in a lucite box at the end of a hallway - had to pass the darn thing easily a dozen times a day. She would not have looked out of place with a box of girl scout cookies under one arm, though I think the statue was actually a guy in military costume, but done at child's scale. Very strange.)
Then, the one we called "road kill" which took up the entire wall facing the receptionists on the 5th floor. I used to wonder how they could manage looking at it all day, it was revolting. It was a large (9 feet long, probably) red metal line, about 2x4 thickness. Underneath was a multi-colored splotch, maybe also in metal, materials unclear. Ick. I can only imagine the thousands it cost.
