This probably isn't what they are called,
And I can't think of the elusive word,
But...I really like bike bells.

You know the ones!
The little diddlydoos on the handlebars of a ten-year-old's bike.
The ones that go
bbbBBBB
      RRRRRrrrrr
           iiiiIIIIIIIIIIIIII
                  NNNNnnnnnn
                 ­      ggggggGGGGGG!

God, they're my favorite.

Because, you see...here's the thing:

When you were a ten-year-old,
Riding a bike to some friend's house your mom didn't approve of,
Did you ever bbBBrrIInnGG the bike bell on your bike when you were upset?

Of course not!

Bike bells are a child's way of telling the world,

"Guys! GUYS! I had a really good day!"

And it makes me happy to know some little kid is so joyful they can't help but bbBBrrRRiiIInnNNggGG all the way down the street.
