After Jurassic Park came out, some paleontologists started measuring Tyrannosaurus rex food consumption in lawyers. If the average attorney weighs 150 pounds, they figure, a warm-blooded T. rex would eat 292 lawyers a year. A cold-blooded one would eat 73. I guess that means they were cold-blooded; there’s certainly no shortage of lawyers today.
