Some songs and partially some textes are written phonetic !
The song CRÉMOÉCRÉMOÉPAS has a textline like this :
T'es-tu athée ? T'es-tu théist ?
I know french, but i don't understand nothing !
Or the song "AMEN" TOÉ says :
Hey toé, réveille toé. Si t'es tanné de t'faire piler sur les pieds !
C'est rigolo !

Of course it's only funny for french speaking people !
