The Anatomy of the Tongue in Cheek (often shortened to Anatomy) is the second full-length album released by the Christian rock band Relient K. It was released on August 28, 2001, and peaked at No. 158 on the Billboard 200. On June 26, 2006, the album was certified Gold by the RIAA for sales in excess of 500,000 units in the United States. The cover of the original release is similar to that of the 1999 Ramones release Hey Ho! Let's Go: The Anthology.
The album continues the band's liberal use of pop culture references (such as the song "I'm Lion-O," which is about the popular TV series Thundercats). Song themes range from pop culture to Christian themes—growth in faith ("Pressing On"), backsliding ("What Have You Been Doing Lately?"), worship ("Those Words Are Not Enough," "For the Moments I Feel Faint," and "Less Is More")—and social themes—such as racism and persecution ("Failure to Excommunicate"), judgementalism ("Down in Flames")—to making excuses or blaming others for one's own faults ("Maybe It's Maybeline"). There is also a song about one's experiences in high school ("Sadie Hawkins Dance").
Gotee Records released a "Gold Edition" of this album on October 31, 2006 along with the release of a "Gold Edition" of Two Lefts Don't Make a Right...but Three Do on the same day. The Gold Edition of this album has remixed and remastered sound is similar to Mmhmm (the album was remixed by the same people who mixed Mmhmm) and it has a music video for the song "Pressing On".
