There’s the La Tomatina festival that happens on the last Wednesday in August in Spain...this is the largest public tomato fight in the world...first of all, why would you do this on a Wednesday?...and second, this seems like an awful waste of food...

No one is really sure where this tradition began, either...we think it started in 1945 when there was a brawl in the main square and one of the few weapons available were the tomatoes on carts of the vegetable stands...

They do something weird in Denmark, too...if you’re 25 years old and it’s Valentine’s Day and you’re single, your family and friends are supposed to throw cinnamon at you...no one really knows why or when this started...but it is a thing...

And how about this...there’s a temple called Sir Saneswar in India...there is a tradition whereby parents who were married at this temple throw their newborn babies from the top of the building...it’s a 50-foot drop...the baby is caught by people holding a big cloth below...I’m sure there are reasons for this, but they all escape me...

Let’s segue to this...rock music has been around long enough—three-quarters of a century—that some we’ve developed some weird habits and behaviors, things that we do just because...

We engage in this behavior or do these things because everyone else is doing it...and if you were to ask around a reason why, no one would have a good explanation...you just accept this thing—whatever it is—as part of the culture...

But what if you really, really want to know?...what if you just can’t take someone’s word that this is what’s supposed to be done?...that’s where this program comes in...This is another edition of something I call “the rock explainer”...
