About 20 years ago when I was in college (yes, I'm old - I already admitted that in the Zappa thread) I lived in a city that had an old abandoned power plant alongside the Mississippi river.
One day while a friend (a PF fan) and I were "exploring" the place, we noticed that the two tall smokestacks had cables attached to them going through pulleys at the top. We managed to get ahold of one of the cables, even though they had been put "out of the way", and it still worked!
That day we started making plans to construct a HUGE paper-mache pig, and hoist it up between the smokestacks as a tribute to Pink Floyd.
Building it would be the easy part. The tricky part would be the logistics. For example, how do you inconspicuously haul a 20+ foot long pig through the middle of town, and get it up to the roof of the power plant without anyone noticing?
We fully intended to do it, but decided we'd have to wait until spring (it would be hard enough without snow).
Unfortunately, before spring came, they tore the power plant down

It still pisses me off just thinking about it. It would have been great!
Of course nowadays nobody would ever think of doing this. They'd just take a picture of the power plant, and use Photoshop to add the pig
So that's why I really voted for Animals.
