Okay, so random question

I both love and hate my coworkers, because they ask good questions, but often I cannot answer them.

Although this is less a question of how to do something and more of a question of what's out there on the 'net.

So, here it is: what is the biggest tail you have ever seen (as made by human hands; no ACTUAL animal tails, please)? It can be part of a fursuit or just a costume accesory that was worn on it's own. And it only counts if it is ONE tail (yes, a kitsune's combined tail mass may be huge, but each tail could be tiny, so that doesn't count).

Also, what is the biggest pose-able tail you've seen? Or what's the biggest tail you've seen with natural sway?

Inquiring nosy office mates want to know! ;)
