A guy comes to the military enlistment office.
He is asked: “What would you like to be?”
He responds:”A pilot.”
So they decide to help the guy and send him to study flying, But he fails. And he comes to the military enlistment office again:
“Sorry, but you can`t be a pilot any more. Select another variant.”
The guy thinks and speaks:
“So I want to be in the air defence.”
“Why air defence?”
“If I can`t fly, then nobody will fly!”
