No!

No! is the first children's album by alternative rock band They Might Be Giants, released in 2002 on Rounder Records and Idlewild Recordings.

Retaining the eclecticism, humor and psychedelic sensibilities of their adult work, the lyrical stylings are decidedly different: the darker themes of death and depression have been replaced with songs extolling the virtues of imagination, robots and sleep. The album declares itself TMBG's first album "for the entire family", with the intention that songs appeal to both young and old audiences. The album contains a cover of Vic Mizzy's safety song "In the Middle, In the Middle, In the Middle" sung by Robin Goldwasser.

No! was released as an enhanced CD; while it plays normally in any CD audio player, it features a CD-ROM portion as well, providing the listener with interactive flash animations by the Chopping Block.

"The Edison Museum" was originally written in 1991 and featured on the Edisongs compilation that year. The recorded version appearing here is largely the same as the Edisongs version, but has been slightly modified. The modified version here previously appeared on Long Tall Weekend in 1999. "Robot Parade" appears in the closing credits of Them, Robot, the 503 episode of the Simpsons.

The largely positive reception the album received led to a collaboration with Walt Disney Records and the Disney Sound label. They released three albums through the mid-2000s, each with a theme: Here Come the ABCs (2005), Here Come the 123s (2008), and Here Comes Science (2009). The band's fifth children's music album, Why?, released in 2015, was intended as a more direct followup to No!
