Cubical doorbell

I got this cubical doorbell at our company gift exchange. Now when people come to pester me,.. I mean, when they come to work out urgent business, instead of screaming at me in crisis mode they can ring the bell first. It has a number of sounds from a cat to ah-oo-ga, but I like the regular doorbell sound. It's the most civilized. The ah-oo-ga sound might be more appropriate though... Ah-oo-ga! Ah-oo-ga! Incoming! Dive! Dive!
