Yep, Elikrotupos is right- that’s where it came up. It was the only in-joke I noticed! 
I totally missed that one. I’ll have to find it once I see it again on DVD.
Elikrotupos: Oh, the ear tag! Now I know why Git is referred to as the “lab rat”! I’ll have to check that out sometime.
As for Colette saying it, I don’t remember that, but I think she did say it sometime. I’ll listen for it next time I watch Ratatouille. 
Ah, it was? Haha, I figured it would’ve been in there somewhere, but I never thought to check.
I’ll have to watch it again sometime
No, Colette didn’t say “A113” anywhere in Ratatouille. Sorry, Elikrotupos. shrugs
I want A113 to be my license plate number!
