who is bobby?

John and I have been pondering this question for some time now. You see, for the past couple of weeks, our little Ruby has been chanting "Bobby, Bobby, Bobby", over and over again. When she wakes up in the morning it's "Bobby, Bobby, Bobby", when she wants something to eat, its "Bobby, Bobby, Bobby". It's "Bobby, Bobby, Bobby", at the pool, in the tub, at church, while mom's on the phone... It's hilarious too, because she repeats it rhythmically and insistently, and even intonates the syllables. Many times she even clenches her fists, and moves her arms up and down (almost like she's pounding them on a table), so we get the full effect. We can't, for the life of us, figure out what it stands for, because she does it for virtually everything, and in any number of circumstances. It's really weird and strange, but also so cute and funny, I almost don't ever want her to grow out of it...Bob-by, Bob-by, Bob-by!
