Shamelessly piggy-backing on @Mousey ‘s pronunciation thread, what are the lines that always make you think, ‘Excuse me? Is that really what you meant to say?’
For me it’s always AC/DC’s Let there be Rock (video link in comments), where Bon declares:
‘One night in a club called the Shakin’ Hand There was a 42 decibel rockin’ band’
Google 40 decibels and you will find it described as the sound of a quiet office, or the hum of a fridge. Certainly nothing that would make you have to shout to be heard above it, ‘And the music was good and the music was loud’.
