I looked for it, but obviously I didn’t look hard enough. I’ll have to wait until I can see it again. sigh
The Pizza Planet truck was really big, almost took up the full frame, I’m not putting it in spoiler tags because it really isn’t spoilerific. Also [spoil]A113 was Auto’s directive, and it appears on his red eye[/spoil]. It shows up about 3 times. This time the inside jokes are easy, and I’m glad.

Yeah, I saw the Pizza Planet truck and was shocked by how easy it was to find…
A113 was pretty much the most obvious easter egg ever.
Really? I was looking pretty hard for it and didn’t see it. Perhaps I was trying too hard, but I guess I can look again when I see it the 2nd time around.
I was happy that at least noticed A113…
Well, I couldn’t find the Pizza Planet Truck in WALL-E, however, I thought my eye caught some other stuff.
Note: This is what I thought I saw. I could be right, I could be wrong.
[spoil]In WALL-E’s little garage, I thought I saw Rex the dinosaur from the Toy Story Movies, and I thought I saw the head of Jack-Jack somewhere in it.[/spoil]
Nah, I don’t think it was Jack Jack. It just looked like a doll’s head.
Didn’t catch anything like Rex though.
Hmm, I don’t know. I thought I saw it. ut there was so much grabage left on earth, anything, even the kitchen sink, could be found.
Spoiler:
It’s on earth, EVE scans the open hood when she is looking for any sustainable life. They quickly cut to a Wide-Shot and you can see it is the Pizza Planet truck all rusted.
I saw the Pizza Planet Truck! [spoil]It’s when EVE is looking for vegetation, and she looks in many different spots. When it appears, EVE is looking under the hood, and then slams the hood down.[/spoil]
FYI use the the spoiler tags. There’s a button on the posting page with all the other BBCode buttons.
Um… I wouldn’t quote the spoiler, Fett 
Hey, kids. Here’s a thread for other Pixar in-jokes in the movie (besides the Pizza Planet truck):
Knock yourselves out. 
That was it?! I can’t believe I missed it!
TSS: You’re right, that is Rex. I read an interview where Andrew Stanton said that it was in the movie. Wow, you’re good!
I’m sinking slowly into the dirt as I say it, but… what is the significance of A113?

Next time I see the movie, I gotta look for the Pizza Planet truck. Just a quesiotn. Was it really noticable like the A113 was?
It is [spoil]stationary, takes up most of the frame, EVE is scanning it, and it’s on screen for only a few seconds in the first 20 minutes.[/spoil]
Conclusion: If you blink you might miss it, but it’s almost as big and obvious as A113.
Okay, next time I watch it, I will try to focus on it.
Actually, the Pizza Planet truck appears in two places in the movie…
First, as it has been pointed out many times, is when [spoil]EVE is scanning various things on Earth[/spoil] buuuut also when [spoil]the projector is attached onto EVE’s head by the Captain to make her display her footage from when she was on Earth, there are a few seconds footage of underneath the hood of the truck, as seen from EVE’s POV.[/spoil] Yeah!
