That reminds me of my jump training, whilst at the door I was a little nervous and didn't want to jump, and the conversation ran a bit like this;
Me "I don't want to jump Sarge'"
Instructor " you will jump Smith!"
Me "But I'm scared!"
he then removed his trousers and waved his tackle at me.
Instructor "by the love of God you will jump Smith, or I'm going to shove this bad boy up you!"
I did jump, but only a little bit at first.
