The Anatomy of the Tongue in Cheek (often shortened to Anatomy by fans) 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 Mmmhmm) and it has a music video for the song "Pressing On".
"Maybe It's Maybeline" (deliberately misspelled, much like the band's name) refers to the popular Maybelline line of beauty products and its tag line.
The title of "Lion Wilson" is a play on Brian Wilson. "Lion Wilson" is the first of many Relient K songs to draw heavily from the style of Wilson and his band The Beach Boys, both of which Relient K lead singer Matthew Thiessen often references as major influences on his music.
The hidden track after "Less Is More" is entitled "Skittles and Combos." The band used to encourage fans to bring Skittles and Combos to shows. While they no longer encourage it, fans still do, and often throw packages to the band. In addition, small packages of each are sometimes placed on the stage by the crew prior to performances. Thiessen also later on admitted that he despised Skittles and had no idea what Combos were.
"Skittles and Combos" isn't on the gold re-release. A different hidden track is at the end of "Less is More" called "The Ballad of Tim Eddings". Tim Eddings was originally the manager for Relient K, and also was a producer for Ace Troubleshooter, the old band of current Relient K bassist John Warne.
Both verses of the song "Failure to Excommunicate" are sung by drummer Dave Douglas, with Matt Thiessen joining in on the first and second verses.
The album contains re-recorded versions of songs from their 1998 demo All Work and No Play. These songs include the ThunderCats-themed "I'm Lion-O" and "For the Moments I Feel Faint", which is a slower, acoustic recording of the song "C.U.R.B.".
The music video for this album is "Pressing On", but the original song chosen for a video was actually "Sadie Hawkins Dance". In the end, they went with "Pressing On", as they didn't have the budget to do what they wanted for "Sadie Hawkins Dance". Matt Thiessen once said this on the band's forum. One plan for the "Sadie Hawkins Dance" video actually included Gary Coleman. 
The resulting video for "Pressing On" shows the band making their way into a building amidst a crowd of fans. Upon arrival, they are greeted by a producer waiting to film a music video with them. When one member asks the director if he can have a drink, he is told that there is no budget for that — a parody derived from the above trivia item.
The song "Sadie Hawkins Dance" once appeared in an episode of the show Smallville.
A tentative track listing for this album originally included the song "Operation", which was eventually used as an exclusive song for The Creepy EP instead.
