Cute. Although there's some truth in that parable, back in the real world, experience in a specific programming language actually does count for something:

1) Learning the intricacies of a language takes some time before you're truly proficient in it.

2) Different languages demand a different approach to problems, a different style of forming the solution. A programmer with 10 years of experience in Ruby and 0 years of C is less desirable for a C programming position than a programmer with 5 years of experience in C. Though the Ruby programmer will be quick to pick up Python, he/she never had to deal with manual memory management, pointer arithmetic, and all the pitfalls that come with those.
