Ooo and I finally got to see Cars again today! Heehee, until now I hadn't noticed the bit during the closing credits where you can see the twins, Tia and Mia (who BTW are Mazda Miatas like in my car icon here), working as waitresses at Flo's V-8 Cafe.
I need to go back and watch the older Pixar movies, also. Apparently the Pizza Planet truck from Toy Story appears in every Pixar movie (including Cars!) but I don't remember all that well what it looks like and I keep missing it.
