Sounds stuck in my head...

It's strange sometimes how something can get stuck in your head from repetition. Like a catchy tune on the radio, the theme song from an old favorite TV show, or in my case tonight the sound of my father's Plectron:

<beep><beep><beep><beep><beep><beep><beep><beep><beep>
<honk><honk><honk><honk>
Allenhurst Police to the Allenhurst Fire Department and First Aid Squad
This is the daily test of the Plectron alarm.
