Argh. The last comment cut out the accompanying picture.

"The 500,000 Finns in Sweden have no rights," he pointed out. 
 

US mean science scores by race/ethnicity are as follows: 
 
489 US average 
523 White, non-Hispanic 
409 Black, non-Hispanic 
439 Hispanic 
499 Asian 
436 American Indian/Alaska Native 
483 Native Hawaiian/Other Pacific Islander 
501 More than one race, non-Hispanic

Scores in the mathematics test were not tabulated by race. US reading scores, as already mentioned, are unavailable. 
 
The racial science scores suggest that the failure of the US education system, as bemoaned in press reactions to these test results, might be more precisely characterized as a failure to educate minorities. The white US mean taken alone would have ranked a respectable 7th in the OECD (10th overall). The mediocre Asian-American mean comes as something of a surprise and I'm not sure how to explain it.

DavidB: There's no sense in comparing the UK's reading score rank (#17 among 56 countries) to the US's science score rank (#21 among 30 OECD countries). You may want to fix that. See table of mean scores.

precise quantitative metric 
 
Yeah, I just wanted to informally explore the subject to see if it might warrant further investigation. Quantitative metrics are important, but I believe that passer ratings have increased too much over time to be of much use in comparing quarterbacks across different eras.

I tried to determine the eye colors of the following all-time great NFL quarterbacks, which I assembled by combining a few "best" lists from the web. (A question mark indicates that I found no clear picture or description.) 
 
Joe Montana - blue 
Johnny Unitas - ? 
John Elway - blue 
Dan Marino - blue 
Joe Namath - blue 
Roger Staubach - blue 
Jim Kelly - blue or mixed 
Sonny Jurgensen - ? 
Dan Fouts - blue 
Bart Starr - ? 
Steve Young - blue or mixed 
Terry Bradshaw - blue 
Kenny Stabler - ? 
Fran Tarkenton - ? 
Y.A. Tittle - ? 
Bob Griese - blue 
Len Dawson - ? 
Archie Manning - blue 
Brett Favre - mixed 
Troy Aikman - blue 
Peyton Manning - mixed 
Tom Brady - blue 
 
Interestingly enough, I haven't yet found a QB on the list with unambiguously brown eyes. The closest so far is Peyton Manning, whose irises are a kind of bluish-greenish hazel with a halo of brown around the pupils.

Razib, can you set up your blog to support video comments? Thanx.

the sheep/human hybrid doesn't seem viable 
 
I don't know. I've seen some pretty hairy Welshmen.
