Sergeant: Private Ramirez, as we make our daring escape, I think it would be a perfect time to review some grammar.
Ramirez: Um, OK, sir.
Sergeant: You are going to learn the difference between "there", "their", and "they're".
Ramirez: Uh, aren't those the same words, sir?
Sergeant: Do those look like the same words to you, Private?
Ramirez: Uh, no, sir.
Sergeant: Darn right they're not. "There" refers to a location, such as do you see that motorcycle over there?
Ramirez: Um, over there near all the bad guys?
Sergeant: Correct, Private!
Now, listen up! "Their" refers to ownership, such as I want you to steal their motorcycle.
Ramirez: You want me to steal their motorcycle?
Sergeant: You're getting the hang of this, Private.
"They're" is a contraction of the words "they are".
For instance, they're gonna be really upset when you steal that motorcycle.
Ramirez: Yeah, they're probably gonna shoot at me, sir.
Sergeant: By golly, you're a regular grammathlete, Ramirez.
Ramirez: So you want me to go over there and steal their bike while they're shooting at me?
Sergeant: That's right, Private.
Ramirez: All right.
Bad guys: Hey, they're stealing our motorcycle! There he is. Hey, we captured their guy!
Sergeant: Wow, those guys are good.
