To be fair, it is a French word, and he's an anglophone from Montreal..

I was hoping it would be Shatner "singing" Sabotage while mispronouncing it.

You're welcome.

I feel like the girl couldn't decide between sabotage or sabotaage and picked something kind of in between to be polite.

Shatner doesn't allow anyone to doubt his deliberate pronunciation!

The related vid is great, need to submit now.
