From another thread:
Flying up from Gatwick to Manchester last night,on landing and while taxinig to the gate the captain finished his address by saying
"Please remain seated until the aircraft has come to a complete standstill and the engines are turned off, this is because we may have to brake quickly causing you all to roll to the front of the cabin, landing at my door and impeding my exit from the aircraft"
Could any of us put it better??
