In Family Guy, what was the second episode where Stewie mispronounces words that irritates Brian?

I know the episode where the emphasize the h in what, why, and whip. Just recently, though, I saw a newer family guy clip where Stewie mispronounces another word. I remember Brian saying something like, "I’m not doing this again." I was wondering if you guys knew the episode it was on?

Stewie was mispronouncing the word Ruin and it was in the episode Love Blactually Season 7 Ep 1. Hope this helps
