It's not quite time to change sigs yet, but here's a statistical anomaly from Phil Plaitt:

"One man's mean is another man's poisson."

I've found it attributed to both Anon and J.W. Haeffner, but Google knows nothing about the latter person apart from a single attribution of this phrase.

I might leave it attributed to the Bad Astronomer, just because it's a more /.y link.
