My husband is an inspiration. He has figured out how to play the national anthem on our electric toothbrush-- simply by by varying how open or closed he has his mouth.
He is also the source of the following little ditty we sing to our son at toothbrushing time. Sung to the tune of "Take me out to the ballgame":
Take me out to the bathroom
Take me out to the sink
Bring me a toothbrush and some toothpaste
I don't care if the paste goes to waste
Let me brush my molars and canines
If they're not clean it's a shame
For it's one, two, three strikes you're out
At the toothbrush game!
Something makes me think that, aside from science, he has multiple callings in life.
