How and when did "aaand he's standing right behind me isn't he?" become the example of MCU dialogue?

I remember a period of time over the last ten years or so where it felt like that joke was happening a lot in comedy movies and shows, but l don't think it was ever really MCU stuff that used that joke.

Is it because all those other projects that used that joke were being criticized for TRYING to be funny like a MCU movie, and now the original thing that all those movies were trying to be is now remembered for being as corny as the stuff that tried to copy it?
