For those who don’t want to read a lot, or dont care too much, here’s the executive summary:
- I’m a long time object programmer.
- I worked for IBM for 31 years.
- I was one of the early adopters/advocates of Smalltalk in IBM.
- I’ve done a lot of Smalltalk.
- I’ve done a lot of standards work.
- I’ve done a lot of Java.
- I’m now free of IBM and Java, and I’m learning to love Ruby.

Five doctors go duck hunting, they draw lots to determine the order in which they will shoot from the blind.
The Psychiatrist gets the first chance.
A flock of birds fly over. He looks down at his shotgun and says
They look like ducks! They sound like ducks! I wonder how they feel about being ducks?
Meanwhile the birds fly by.
Next up is the internist:
They look like ducks! They sound like ducks! But we can’t rule out the possibility that they might be geese.
Then the general practitioner:
They look like ducks! They sound like ducks! What do you guys think?.
The surgeon takes his place next. He confidently feels the trigger of his shotgun with his highly skilled right forefinger. The next flock flys over.
Bang! Bang!
And the surgeon turns to the pathologist and says:
Check them out and see if they are ducks.
I’ve known this joke for quite a few years, but I’ve never thought about it in relationship to software, until I started playing around with Ruby, and discovered an old friend under a new name, “Duck Typing.”
