Bing search results are a cheap imitation of Google's

Amit Singhal has posted an in-depth description of Google's sting operation which was carried out to investigate whether Microsoft's Bing search engine has been using the Google search results to fine-tune its own search results.

Amit Singhal has told the SEO blog that Bing is "pure and simply cheating"
