Most interesting uses for Bard's ultimate that you've seen?

Just wondering what crazy stuff you've seen or done with this awesome spell.

Just got out of a game with an enemy Wukong, he tried using his decoy to block a Caitlyn ult like most would do, So I ult the decoy and the shot goes right on through to the real Wukong.

He was laughing like crazy after me doing that.
