The raccoon looks like he is happily jamming to his favorite AJ tunes!
In World War 2 headphones were used to communicate. It turns out they were first used in the military! (My grandfather was in the military.)
According to AJ:
" The first headphones weren’t even headphones. They were a single piece simply called an earpiece. The earpiece was the only way to listen to electrical signals before amplifiers were made or what we call today, a stereo."
Wow! Isn't it weird how things always seem to start out simple and then turn into something big.. EXTRAORDINARY?
