Yarn: search for a snippet of dialog, get a clip from the movie it's in

Yarn does one thing very well: return a brief video clip of a movie based on the dialog you type in.

I especially like that if you paste in a URL, you get an automatic subtitled GIF that links to the video instead of the full embed. A real USDA grade A GIF image, not a bottom-quality mpeg hacked into its mime type or some other shenanigan that makes it effectively impossible to repost.
