Yonks ago my younger brother (RIP) used to help me with memorizing my 727 phase 1 drills. Invaryably "fire the bottle" came up during the engine-fire drill and once he asked what it was.
I asked him what did he think? He was a 6yo at the time.
He replyed that he thought he was a man you automaticaly sacked if a planes engine caught fire -
"Hey BOTTLE! Into my office! NOW!"
"Yes sir. Im here Sir."
"You caused that engine to burn! YOUR FIRED!"
Pissweak I know but he was a funny little bloke when he was explaning it. Earlyer with the F27s "HP cocks to lockout" he thought I had to lock our chooks out of the house.
