Apple's latest ad is about a New Orleans barber shop that gets a viral boost thanks to some well-placed headshots.。

But if you look closely, there is one guest who might look a little familiar. Albert Einstein makes a cameo among the shop's diverse influx of new clientele. 。

Aside from the famous scientist, Nigerian funk musician William Onyeabor, the man behind the ad's soundtrack also gets a trim. And a newscaster from a television set within the ad makes an appearance in line. 。

Thanks for signing up!。

Apple says the haircuts are all real, and the clippings were donated to the charity Locks of Love. 。
