It’s not a parody, but a direct ripoff, um, I mean homage to the character actor who made his whole career out of that line. This question comes up here every month or two, but for the life of me I can’t remember his name. Frank something?
The actor is question is Frank Nelson.
Robot Arm, just a guess here, but could it have anything to do with Blondie’s dog Daisy?
Zenster - I got the Pennsylvania=Transylvania thing. I was just providing background to the episode, so everyone would know what Iw as talking about.
But, good explanation anyway. 
Twenty bucks says someone is going to ask about “Sneed’s Feed and Seed (Formerly Chuck’s)”
I believe the “Daisy had puppies” is just a humorous unexpected non sequitor. We’re all here overthinking Simpsons jokes, and often missing the all-too-obvious humor.
Now as for missing humor, I saw Willie rubbing Ajax on his armpits with a brillo pad. I must confess that I do not know what ajax is, being the sheltered individual that I am…
Ajax is an abrasive cleanser; like Comet (if that helps any). Check this link and scroll down to the directions.
Now I get the joke!
I don’t get it.
Sigh. Here’s your 20, I’ll be the idiot.
I haven’t watched the Simpsons more than a few times in years but out of a perverse sense of something I read the threads and this is the second time I’ve seen this one.
Since the first thread referred to being surprised the censors left it I assume it’s sexual. Inform me.
feed and seed rhyme with sneed. now what would you have to change the last 3 letters in each of those words to to get it to rhyme with Chuck?

Sneed’s Feed and Seed rhymes. What would a similar rhyme be if the name was Chuck’s?
Insert inevitable smily here: :smack:
Thanks.
Now if somebody would just start a thread about double entendres and movie references in Pokemon I’d be all set. (OK that’s because there’s only a few but I’d be set)
It gets listed as “Brevity…is wit”. 
In the episode where Homer and Grandpa go into business making love potion, there’s a scene where they’re doing a “Step right up…!” sales pitch and there’s a really goofy guy in the audience who says something like “but I’m unsure of aphrodiaics”- who is he supposed to be? he seems so familiar- old 50’s cartoon character?
You know what bothers me? When someone in an “explain this joke to me” thread references a joke they understand, but don’t explain.
For the record, the correct post is:
For anyone who missed it, “Sneed’s Feed and Seed (Formerly Chuck’s)” is a joke to get around the censors. Chuck’s store was called “Chuck’s Fuck and Suck”.
Okay, there’s a flashback episode where Homer is a pin-monkey at the bowling alley. At one point he has to figure out how to bring in more business. There is a scene where he’s brainstorming that has a lot of unusual “shots” that tend to make me think it’s a movie reference, but I don’t know what it’s referring to. And I think I looked it up before, too.
I’m embarrassed to ask, but could someone explain why the “Ayn Rand School for Tots” scene is so funny? I’ve read The Fountainhead but that’s all I know about Ayn Rand.
In the Halloween episode, “Time and Punishment”, Homer shouts “I’m the first non-Brazilian to travel backwards in time!” I don’t get it.
I’ve asked this before and been told it’s just a random throwaway line. I’m half-resigned to this possibility, but a nagging little voice tells me it has to refer to something.
And Carlos Castenada and Don Juan were North American, so it ain’t them.

Here’s the episode guide for that episode. I vaguely got the joke, but wouldn’t be able to communicate well at all. They do a pretty good job:
Sublight:
Their guess is that it was a reference to Carlos Castenada:
Ayn Rand was a pretty severe and austere gal, who never had any children of her own (her own mother’s description of motherhood as “a hateful duty” may had something to do with it). Maybe more importantly, her books are creepily 100% devoid of children; all characters good and evil alike are childless, themselves apparently having sprung fully grown from Zeus’s forehead or some such. Childrearing didn’t appear very high on her list of worthwhile pursuits. Rand was really, really big on self reliance and thought altruism a worthless virtue, kind of the opposite of what you’d expect at school for tots: “Change your own diaper, parasite!”
