The albumThe Best Day Ever was written by SpongeBob's voice actor, Tom Kenny, and producer Andy Paley. Featuring 27 tracks, it was influenced by the 1960s pop music. The record's numerous skits refer to a freeformradio station called WH2O. Kenny's inspiration for the song "My Tighty Whiteys" was "underwear humor". Kenny said "Underwear humor is always a surefire laugh-getter with kids Just seeing a character that odd wearing really prosaic, normal, Kmart, three-to-a-pack underwear is a funny drawing We thought it was funny to make a really lush, beautiful love song to his underwear." In addition to the cast, the Beach Boys' Brian Wilson, NRBQ's Al Anderson, Joey Spampinato, Tom Ardolino, and Terry Adams, and Tommy Ramone of the Ramones were musical guest artists. Kenny said, on the musical cameos, that "We thought they would spread some magic dust on it. And although this is just a weird little cartoon record, I didn't want to have today's equivalent of Kajagoogoo or Men Without Hats on it." He opined that "the people we got" are "kind of timeless." Other musicians who contributed to the album were Dave Allen, Don Allen, Mandy Barnett, Jerry Blavat, Mike Bolger, Corky Hale, Lisa Hammon, Flaco Jiménez, James King, Tommy Morgan, Jillinda Palmer, Herb Peterson, Nino Tempo, Mike Uhler, and Jeremy Wakefield. Brian Wilson provided backing vocals for the song "Doin' the Krabby Patty". Originally, Kenny and Paley were working on a "Brian Wilson-esque" song with "Brian Wilson-esque" background vocals on it. Kenny said "and at the last minute, we had this opportunity to reach out to him and ask if he'd do it But Brian's people said he was going on to Hawaii the next day with his wife and kids, and then going on the road." Eventually, Kenny got a call from Wilson saying that "I loved the idea." Elvis Presley's guitarist James Burton performed the guitar in the song "You Will Obey". Kenny said "One of our hidden Easter eggs that hopefully more than three people in the world will get is during the guitar solo when Plankton says 'Take it, James', which was what Elvis said in every one of those concert movies."
Reception
The album received mostly positive reviews. AllMusic gave the album a score of 4 out of 5. In his review for the IGN, Spence D. gave the album a 7/10 score rating it as "good". He said, "parents who grew up in the late '50s and '60s will get a kick out of the musical tributes to the music of those eras and perhaps listen along with their kids during a family fun time extravaganza." Geoffrey Himes of the Baltimore City Paper said "How do little kids respond to this record? I wouldn't know; there aren't any little kids in my house. You don't have to be a parent to enjoy the killer hooks and lush harmonies on this disc. All you need is the courage to ignore the raised eyebrows of your friends." Kerwin So of Common Sense Media gave the album a score of 4/5. However, So claimed that the album is full of consumerism and said "Parents need to know that although the physical packaging of this CD contains a lot of advertisements for other SpongeBob products, the songs themselves contain very positive content and steer clear of commercialism." Chris Willman of the Entertainment Weekly opined that the album is "not quite a teenage symphony to God." He called the song "My Tighty Whiteys" "the most obvious nod to the Pet Sounds sound." According to him, " two of the best songs are garage-rock anthems" which includes "Under My Rock" and "You Will Obey". Willman said that Plankton's performance in the latter "sounds like a little like Eric Burdon, from the Animals, turned fascist." He gave it an "A-" rating and recommended it for ages "4 to... 94!" In a 2014 review, The A.V. Club ranked The Best Day Everalbum 3 in their list of "13 novelty albums recorded by TV characters". The publication called it "a charming throwback" when "TV character novelty albums have faded away in recent years."
