Oh, tracks like animal tracks!

I have to admit, too, (you folks are really going to get the idea that I MUST be a blond), that it took me awhile to learn what a Bluetooth was. I'd hear people seemingly just having a conversation with someone who wasn't there.
related joke:
I told my shrink that I had a bad tendency to go around talking to myself.
He said, "That's okay. Just hold your cell phone against your mouth!"
Man, I sure seem to be striking out with my humor lately! Not one dad-blasted "thank you"! Oh, well....
