Probablility

I used to have 2 work keys, both nearly identical. When I picked a key, I'd get the right one about half the time. Exactly what you'd expect.

Now I have 3 work keys, all nearly identical. When I pick a key, I get the right one about zero percent of the time. When I pick a key from the remaining two, I get the right one zero percent of the time.

This feels like a Dirk Gently scenario.
