In the days when your 'terminal' was a telytype machine, hence no on-screen corrections, you had to be creative when accepting input.
I remember well when I had forgotten how to exit from a certain utility. I tried Exit, Quit, Bye etc all to no avail. Finally in desparation I typed F*** Off - bingo it worked!
The savvy author of said utility only looked at the last 3 characters in input thus ignoring typos in the middle.
