Juicy Footnote?

I seem to remember reading a footnote in a Supreme Court opinion some time in the last year and now cannot locate it to save my life, especially now that my Lexis and Westlaw passwords died. Relevant half-recalled details:

1. I think it was a Stevens opinion.
2. It pertained to either statistics or economics.
3. The gist was something like "my clerk X, who is actually literate in the field, tells me that the correct mode of analysis for this case would be Blah Blah Blah."

At the time I thought it was sort of funny, but now it's just bothering me that I can't find it.
Help?

UPDATE: Thanks to Jenn. It's note 5 in the annoying Hazelwood opinion.
