As part of its three-year anniversary celebration, PolitiFact Founder Bill Adair posted a fun look back at its beginnings, which noted its popular Truth-O-Meter's fact-checking of pundit and politician comments.

Adair revealed the top five most popular Truth-O-Meter reviews of the past year, with two of them involving Glenn Beck statements deemed “false.” The most popular, as the list shows below, was when bloggers declared millions had attended a Tea Party event last September. That earned a “Pants-On-Fire” rating.
