It’s a song. The rhythm’s dactylic*: Dee diddly diddly diddly dah - ‘And teach you/ to never/ say never/ again’. The metrical requirement of the tune forces the wording (which, as a result, sounds forced).
*PS: Trivium of the day – as in ‘pterodactyl’ [‘wing finger’], the word ‘dactylic’ is to do with fingers: you can think of it like the bones of a finger – long short short.
