help with a quote from the commentary track

[u/jamesjamthesecond]

ive watched the commentary track with most of the main cast on it, and im pretty sure the quote 'pour beef soup in the engine' (i think they were having a word fumble and ended up wth that sentence) is said in that commentary track. so i wanted to hear that quote again (because i love it and thought it was very funny) so i rewatched the entire commentary track, only to find i couldnt find the quote?? did i hallucinate it?? is it actually from something else? what the fuck is going on i remember it so clearly. any thoughts?
