Color is usually some shade of yellow and often varies with the concentration of the sample. The most common color descriptions of normal urine are straw, light yellow, yellow and dark yellow. Amber colored urine is seen in patients with increased bilirubin levels and may indicate hepatitis.
Add the knowledge of bowling's perfect score, 300, and it stands to reason 10 strikes in a row is a perfect 300.
The national average average is in the high 170s, if you took a poll here you'd probably see an average average in the 190s if not higher. Nationally, probably 3-4% of bowlers have an honor score, here it's easily double digits.
