Origin of "You made my day!"

Solution 1:

Etymonline only has a date:

To make (one's) day is from 1909; menacing make my day is from 1971, popularized by Clint Eastwood in film "Sudden Impact" (1983).

The Phrase Finder has this:

Dirty Harry wasn't the first to use the phrase ["Make my day"] with that meaning ["Carry on with what you are doing — it will give me an excuse to behave badly"] though. It had been spoken earlier by the character Tom Walsh — played by Gary Swanson in the film Vice Squad, 1982. In that film the line was, "Go ahead scumbag, make my day".
