Sounds like the tease of a very interesting story. I'd love to know how you did that.
I was worming my show mare and she was a bad head tosser. I uncapped the tube and had it sideways in my mouth. I was trying to hand twitch her nose and the heifer went up and flung me to the ground. Some how or other the tube got turned and I had the business end in my mouth. When I hit, the plunger did too and I was wormed.
