Not true. I'd always believed that one, too, until I took a direct hit from one under a belly mower.[:'(][:@][:'(] Also, NOTHING takes the smell away. I tried tomato juice, vinegar, gasoline, etc. After a couple hours, my sense of smell was pretty much use to it, so it didn't bother me anymore. Although everyone else seemed to think I stunk for about a week or 10 days.
