Ok, so this is how my mind works, for better or for worse (probably for worse).
Amanda and I are watching the prelude to the Kentucky Derby and they announced the crowd at approximately 156,000 people and said it was the third largest in derby history. Immediately I thought it'd be funny if they were meaning largest in terms of body weight rather than body count, so I had to figure it out.
According to National Center for Health Statistics the average weights are:
Male : 189.8
Female : 162.9
If you figure that half the people at the derby are male and the other half female that equates to a total mass of 27.51 million pounds worth of people at the derby. I'll have to keep tabs on the total for next year, see if that crowd is "larger".
