Twenty years ago today, the world changed. Food tasted better. The air smelled a little fresher. Life just improved overall. MC Hammer released his single U Can’t Touch This on Jan. 13, 1990.

Think about it. Twenty years and one day ago, no one knew about Hammer pants and after hearing the command “Stop,” no one replied “Hammer time!” Sure, Hammer had some success before 1990, but he didn’t take over the world until this song came out.

You know the video. You know the dance. You might even know the Firefox add-on for your computer. So turn on the song and pay tribute to one of the greatest days in U.S. history.
