Homer: Lisa, when you get to be our age, you learn a few things. Like when a sign says 'Do not feed the bears' (holds up his arm with a bear cub having its claws and teeth sunk into it) man, you better not feed the bears.
Bart: Mrs Krabappel, I can't take the test, I have a stomach ache.
Grampa: Well, it does! [points at Maggie] Aaaahhh! Gah! There it is! DEATH!!!
Lisa: It's only Maggie.
Grampa: [chuckling] Oh, yeah. You know, at my age, the mind starts playing tricks. So...AAAAAHHHH!!!! DEATH!!! [points at Snowball II]
Lisa: That's only the cat.
Grampa: Oh. [points at Maggie again] AAAAAAHHHH!!!! DEATH!!!
Lisa: That's Maggie again, Grampa.
Grampa: Oh. Where were we. [points towards something, probably the door] AAAAAAAHHHH!!!! DEATH!!!
Homer: Lisa, honey, if you really want to preserve his memory, I recommend getting a tattoo. [rolls up his left sleeve] It preserves the things you love. [notices his tattoo] Starland Vocal Band? They suck!
Grampa: [outside, still obsessed over death "stalking him", pointing at the bird bath] AAAAAAAAHHHH!!!! DEATH!!!
Homer: And I won't rest until I've gotten a hot dog!
