Root Beer Float

I know, you're probably wondering why am I posting something that everyone, even a child knows how to put together.  Well, I remember that when I first came to the U.S. I had no idea what a root beer float was.  So, I'm posting this for all of you out there that don't know what a root beer float is.  Is extremely easy to make and VERY yummy.  And the name comes from the fact that the ice cream floats in the root beer. :)  Enjoy!
In a tall glass, place a couple of vanilla ice cream scoops.  Top with root beer.  Enjoy!
