Fry: But won't that change history?
Professor Hubert Farnsworth: [ultra sarcastic] Ohh, a lesson in not changing history from Mr. "I'm My Own Grandfather"! Let's just steal the damn dish and get out of here! Screw history!

My favorite all come from the same episode...
Leela: It's amazing that your people can fall in love so fast.
Dr. Zoidberg: Love? That word is unknown here. I'm just looking for a female swollen with eggs who will accept my genetic material.
Fry: You and me both, brother!
Fry: So you have to choose between life without sex and a hideous, gruesome death?
Dr. Zoidberg: Yes.
Fry: Man, tough call.
Fry: Now, ask her how her day was.
Dr. Zoidberg: Why would I want to know?
Fry: You wouldn't. Ask anyway!
Dr. Zoidberg: How was your day?
Edna: Well, first I got up and had a piece of toast. Then I brushed my teeth. Then I went to the store to buy some fish...
Dr. Zoidberg: Fry, look what you did! She won't shut up.
Dr. Zoidberg: This "love" intrigues me. Teach me to fake it.
Dr. Zoidberg: I'm confused, Fry. I'm feeling a strange new emotion I have never felt before. Is it love when you care for a female for reasons beyond mating?
Fry: Nope. Must be some weird, alien emotion.
Literally all of that is in one episode...
