This video is so good, some people think it’s a sly commercial for Nokia, but it’s not – this actually happened.

Slovakian classical violinist Lukas Kmit was giving a fancy recital when, right after finishing a piece, a Nokia cell phone went off with its distinctive Nokia ringtone. After a brief angry glare, Kmit decided to do a little musical improvisation around the Nokia theme.

Result? Applause.

But here’s something you may not know: The Nokia ringtone is actually taken from a piece of classical music itself – Gran Vals, originally written by Spanish classical guitarist Francisco Tarrega in 1902. Use that little bit of knowledge to impress the hell out of your date.

(I’m guess Kmit knew that, though. Showoff.)
