Homer Simpson: Marge, in every marriage you get one chance to say, "I need you to do this with me." And there's only one answer when somebody says that.
Marge Simpson: OK Homie, I'm with ya.
Homer: Thank you my sweetheart.
Bart Simpson: Mom?
Marge: Yes honey?
Bart: You just bought another load of crap from the world's fattest fertiliser salesman!
Homer: I'll teach you to laugh at something that's funny!
EPA official: Sir, I'm afraid you've gone mad with power.
Russ Cargill: Of course I have! Have you ever tried going mad without power? It's boring. No one listens to you.
Cheif Wiggums: Sorry, no dumping in the lake.
Fat Tony: Fine. I'll just take my yard trimmings into a car compacter. [Walks away.]
Eddie: Sir, I think there was a dead body in there.
Cheif Wiggums: Yeah, I thought that too, until he said 'yard trimmings'. You gotta learn to listen.
Homer Simpson: Hey, Marge! Isn't it great being married to somebody who's recklessly impulsive?
Marge Simpson: Actually, it's aged me horribly.
Tom Hanks: Hi, I'm Tom Hanks. The government lost its credibility and is borrowing some of mine.
Marge: What's the point of going to church every Sunday if someone we love has a genuine religious experience we ignore it? Right Grandpa?
Grandpa: I want bananas on my waffles!
Homer: I can't believe we're paying for something we can see on TV for free.
Eddie: Hey kid, I know no one likes to wear clothes in public, but you know, it's the law.
Flanders: Would you look at that. You can see the four borders of Springfield; Ohio, Nevada, Maine and Kentucky.
Ned Flanders: Uh, Homer? I don't mean to be a nervous Pervis, but if he falls, couldn't that make your boy a parapleg-erino?
Homer Simpson: Shut up, Flanders.
Bart Simpson: Yeah, shut up, Flanders.
Homer Simpson: Well said, boy!
Marge Simpson: Bart, are you drinking whiskey?
Bart Simpson: [drunk.] I'm troubled!
Bart Simpson: Dad! It's not fair to use a bug zapper to catch the fish!
Homer Simpson: If you love fish like I do, you want them to die with dignity!
Bart Simpson: This is the worst day of my life.
Homer Simpson: The worst day of your life *so far*.
Answer: Homer has been known not to make the smartest decisions, and the decisions he does make, he makes without fully thinking them through. Clearly he wanted to get some donuts as quickly as possible without thinking of any other ways, so he decided to ditch the silo in the lake as it would be the fastest way of getting it off his back, even if it's not the smartest. Also, putting that aside, he likely wanted his own pick of the donuts rather than have Lenny guess what he wanted.
