I Hope the Verbal Bicycle Bell Has a Curse Button

I don't know how effective the Verbal Bicycle Bell is compared to a regular bell or your own lungs, but it claims to generate 80 decibels with its 44mm speaker. It screams "On your left!" and holds a 20-second recording.

If you install it on a fixie, it can also talk in faux French. [Hammacher via The Fancy]
