Written and composed by Sylvain Lebel and Dominique Pankratoff, "Les Bêtises" is a song recorded as a nursery rhyme.

Elia Habib, an expert of French charts, stated it is full of mischievousness and could be subtitled "the rhyme of a calamity" as, in the lyrics, "the performer tells the disasters which she carried out to punish her boyfriend for having left her".

Produced by Teetoff, the song was the second single from the album Mon monde à moi and was released on 2 June 2006.

In 2010, Les Enfoirés recorded a cover of the song for their album La Crise de nerfs!

; the singers on this version are Jean-Louis Aubert, Zazie, Jean-Jacques Goldman, Jean-Baptiste Maunier and Jenifer Bartoli.
