Mater: I didn’t do it officer, I swear!
Toy Story 2 reference. 
The Ghostlight’s gone‽
Mater: Oh my goodness, serious stage fright!!!
MATER: Beware people! I think Gazerbeam’s ghost is behind me!
Oh, I never thought of that one. Really clever bbd!
Okay, here’s one for that Mater one:
song playing in the background “It’s the end of the world as we know it…and I feel fine…”
Mater: HELP! Syndrome is using his immobi-thing on us! AH!!!
Funny ones guys!
MATER: Don’t look into the light, don’t look into the light…ah, I looked into the light! Curse my rearview mirrors!
Try this one you guys!
BUZZ:I will not tap the glass, I will not tap the glass, I will not tap the glass…oh, who am I kidding; Rex looks weirdly laughable.
Rex: YES! I deafeated Buzz in Super Smash Brawl!!!
This is what happens when you bring a prehistoric creature into the futuristic space ranger world.
Rex: To infinity and beyond!
Buzz: Why are you wearing that? Can you breathe?
(Rex plays dress-up shopping)
REX: How do I look? Is it on right?
BUZZ: Perfect fit. That’ll be eight dollars.
Remy: Emile! Hey, I want you to meet my new friend, Thomas. Say hi to Emile, Thomas.
Emile: (scared) Ummm.
Remy: Emile, have you ever seen anything cheesier than this!?
Emile: Uuhhh, this caption comes to mind.
REMY: Say cheese!
EMILE: OK…now it’s my turn to say, ‘what is that’?
REMY: Don’t be rude- it’s a cheesy camera!
Remy: You know where the future is, Emile? Cheese!
Emile: …
(this caption is for the Toy Story 2 one)
REX: OMG, the new WALL-E sneak peak is on! Good thing I got my space fan helmet!
BUZZ: EVE is beautiful…
(now for the Ratatouille one)
REMY: YES!! Food! After days of searching…
EMILE: You know, you could have borrowed some of mine…
