With reference to the Gear Up call I once had to endure the response 'selected, 3 reds' followed by 'gear is up, lights out'.
No one ever told me what to do between then and until after final clean-up if there were only 2 reds. Hold the checks, maybe?
At the risk of thread drift, other useless classics include during takeoff 'temps and pressures checked' , 'on finals, no flags' and in response to the 500ft rad alt call 'for the threshold'.
