Fran: I've made a decision, you're not throwing my mother.
Earl: I'm throwing her, Fran.
Fran: You want to sleep on the couch the rest of your life?
Earl: I'm throwing her, Ethyl! I'm throwing her, I'm throwing her, I married you so I could throw her. (edit) (looking through photographs)
Robbie: This is when you came to visit me at camp, here's a letter I wrote. "Dear Grandma, how are you? I am good, the food here is good, I hope you are good too. (both laugh) Love, Robbie Sinclair.
Ethyl: Yeah, yeah you always wrote me. (edit) Robbie: It used to be old dinosaurs slowed down the pack, now we live in houses. It used to be old dinosaurs couldn't hunt, now we have supermarkets. So isn't throwing Grandma off a cliff just a waste of a perfectly good old lady? (edit) Robbie: Dad, when Grandma goes into the tar pit, is there life after that?
Earl: For me there is. (edit) Fran: I want you to think of the tar pit as a wonderful place where you'll want to spend eternity.
Charlene: Oh, I get it. Just like the Galleria.
Fran: (sarcastically) Yeah. (edit)

Mister Ed

While watching TV, a commercial comes on for Mr. Ugh. About a dinosaur who owns a caveman that can speak.

This is a parody of Mister Ed, a show about a man who owned a horse who could talk. (edit) La Brea Tar Pits:

When Robbie asked about the tar pits, Ethyl said they were named after a dinosaur named Bob La Brea.

This is a reference to the famous La Brea Tar Pits in the Miracle Mile district of Los Angeles, CA. (edit)
