Mean Coach Whistle

Origin
The precise origin of this artifact is unknown, but it is presumed to be an overly aggressive gym coach.

Effects
When worn, the wearer will become very aggressive in their attempts to engage other people in physical activities. They will also have a great tendency to use derogatory names when addressing others, regardless of whether they previously liked them or not.

When blown, those who hear the whistle, sans the wearer, will suffer increasing fatigue every time the whistle is blown. However, they will be compelled to contnue the physical exertions until they collapse from exhaustion.

Collection
Collected by Arthur Nielson in 2001 from [REDACTED] elementary school, along with a cache of other artifacts.
