A few weeks ago we were holding short of RWY 28 at SYR (flow into PHL... imagine that) and I noticed out the left side there were dozens of pink flamingos. If you have ever been to SYR you know that there are flamingos in the grass in the summer and penguins in the winter... I have no idea why. Obviously fake, but I just had to call the FA and tell her about them. I never mentioned whether they were fake or real, but she assumed they were real and proceeded to inform the passengers... she was really mad me when she realized they were fake! Those passengers must have thought she was crazy!
