Who knew cows loved trombone music so much?
In this clip, Farmer Derek Klingenberg manages to attract an entire herd of cattle by simply playing Lorde's "Royals" on his trombone.
If you're the impatient type, skip ahead about a minute to see the first cows appear on the horizon. It's not long before some of the cows aren't just trudging toward the music -- they're flat-out running for it.
Maybe the music just mooooooooves them.
