I thought I was seeing things a while ago on the M8.
There is a Pyramids Business Park, with (you've guessed) a row of pyramids parallel with the road. I wasn't driving and suddenly saw a load of red sheep. I wondered if I had imagined them, but no, on the way back, the existence of red sheep was confirmed.
Funky, aren't they?
Apparently it was all done for a bit of a laugh. You can find the full story here.
Now the same business park has 'set free' a giant red stag in the same location... but apparently that statue has a history of changing location, or as quote in the BBC story puts it, "He's a bit of a wanderer so I'm not sure how long he'll stay at the Pyramids for and I wouldn't be surprised if he popped up somewhere else in the near future."
