Woah!! We really don't need that many samples. We only need two or maybe three of the most representative real-world usage examples of the language. You also need to reference where the samples come from and the license they're covered by in the template in the OP.

We also don't change or remove samples already added, which raises the question: why are you removing the current sample?

@lildude - I reverted the "sample" change - I wrongly assumed that more was better somehow!
