Big Bird Flu?

I've got your pandemic right here, boys and girls. One of these things is definitely not like the others. Has Big Bird ever been more sinister looking than this representation? It makes me reconsider a lot of things I thought were true. Like Mr. Hooper. How did he die? Bird seemed awfully confused by it... almost a little too confused now that I think about it. Hmmm. And don't get me started about how long it's been since we've seen Guy Smiley or Roosevelt Franklin on the Street.
