My Tuner must be broke!

Ok, so where's my tuner knob, the one that lets me change stations, lets me change the signals I can receive and broadcast? I have a squeaking guinea pig, a whiney child, 2 other demanding children & Brian is listening to some show about rock music.. I can't seem to tune them out. I don't know how people can do that, I am jealous! So off I go to get them all settled down.. and see about getting that damn tuner fixed!
