What is the first instance of the “go on three” cliche? Where two characters are about to do something daring, and one says “on the count of three!” He starts to count, and the other person says “You mean one two three go? Or one two and go on three?” Mild hilarious confusion ensues. How many instances can you name? Curious about its prevalence.
I think the first use must predate all the suggestions so far, going back into old movies. I can’t think of a particular case but it seems to have been ingrained in the language when I was a child many many moons ago. But perhaps I was fooled by it’s rapid adoption as a trope more recently.
And then there’s the version where someone (e.g., a doctor) has to do something painful, like relocate a shoulder, warns the patient “this is going to hurt. I"ll do it on three…” then says “one…” and relocates the shoulder.
This is pretty well known by now, but it fits here. In Die Hard, they got the shocked reaction on Alan Rickman’s face by telling him they were were going to drop him to the air bags on the count of three, but instead dropped him on one.
