What Could This Mean?

So our baby boy is on the way and this is just too funny to not post about.

Melissa was driving alone running an errand and she had the radio on. Back in Black came on and she turned it up. The baby started kicking her!

I heard what happened so I played the song at home on our computer and sure enough, he started kicking again! HA!

Maybe Angus is a good middle name for this kid?
