Film Sound Cliches

Some good ones including:

*Dolphins always make that same "dolphin chatter"
sound when spinning, jumping, etc

*Snakes are always rattling

*Bombs always have big, blinking, beeping timer
displays

*Every helicopter shutting down emits the
chirp-chirp-chirp sound of the rubber drive belts
disengaging, in spite of the fact that only the famous
Bell 47G (the M*A*S*H chopper) actually makes this
sound

*The first spoken words in a microphone must be either
'Testing, Testing' or 'One Two,One Two'
