Garry Hoy
I always forget this guy's name when Darwin Award discussions come up, but Garry Hoy might be the greatest Darwin winner of all time.
The Story
To learn the circumstances of Garry Hoy’s death, one might initially get the impression that he was either stupid, under the influence of drugs or alcohol, or perhaps even suicidal. Nope, he was just an over-educated braggart.
Garry Hoy was a respected Toronto lawyer and philanthropist, but sadly he is now mostly remembered for his embarrassing death. While attending a reception for new articling students, Hoy decided to demonstrate the strength of the boardroom’s “unbreakable” windows by throwing himself against them. Unfortunately, they proved less indestructible than advertised and the lawyer plunged 24 stories into the courtyard below.[1] 
But that's not the whole story. The glass didn't break, the frame holding the glass in place did.[2]
Aftermath
Hoy’s tragic death also possibly sealed the fate of Holden Day Wilson, the law firm he worked for. In the course of three years, there was a mass exodus from the firm; more than 30 lawyers left after the trauma of losing one of their own.[3]
In 1996, Holden Day Wilson officially closed due to issues surrounding unpaid bills and compensation. At the time, it was perhaps the most infamous law firm failure in Canadian history.
