The Master Blog periodically lists people who completed their Microsoft Certified Masters Program in various disciplines, such as SQL Server. In case you are not familiar with it, the Microsoft Certified Master Program is much more challenging (and expensive) than the more well-known Microsoft Certified I.T. Professional (MCITP) certifications.
In the SQL Server version, you must have at least five years of hands-on experience with SQL Server 7.0 or later (including at least one year on SQL Server 2005 or later). You also must have both an MCITP: Database Developer certification and an MCITP: Database Administrator certification. Then, you pay $18,500 for three weeks of training and exams with Kimberly Tripp and Paul Randal in Redmond, where you have to pass both written and lab-based tests. If you make it through all of this, you will have your Microsoft Certified Master.
Here are some people who have done this:
