I had an arm lengthed glove I wore oncet upon a timer. My friends dad was trying to teach us how to check a cow to see if it was pregnant. Arm went in all the way to the pit, displaced processed food in the process. I did that once--once, learned my lesson. Don't know if I could do the thumb thing on a vicious dog though. You sir, are brave.

BTW after checking that cow, I had to go home and take a shower and get fresh clothes. One lesson I was taught, was to never go over to Shane's house on an early Saturday morning when his dad was home.
