An important message from Jacob Lee Karlin

I replay Jacob's "Hi!" all the time in my head while I'm daydreaming at work, and it always brings a smile to my face. It's really weird to hear his true voice. For the past few months he's been grunting, squealing and whispering under his breath in the form of "dada" and other consonant sounds. But those sounds, to me, are different from the word he just created through his finely-tuned vocal chords.

Can't wait to hear what comes through those high-pitch pipes next time. I hope it won't be anything inappropriate.
