Poll: Oldest protein anyone has been dumb enough to eat?

[Crash]

What's the oldest protein or weight gainer anyone has been brave, cheap, or dumb enough to eat? I just found some weight gain powder in the closet that's 2 years old. I wouldn't dare eat it, but still. I bet many of you out there have been desperate enough to try it.
