Chalkboard: Jesus is not mad His birthday is on Christmas.
Couch: Repeat of the opening sequence and couch gag from "Kill Gil, parts I & II" where The Simpsons are in a Christmas tree ornament (only the music playing when the scene pans out to the Christmas tree is "O, Christmas Tree", not "Deck the Halls")

Jimbo: Nice prank, Simpson. I dare you to dump that bees' nest on those second grade babies.
Bart: Why would I want to?
Jimbo: Because I said "I dare you." Kearney, can you read it back?
Kearney: (reading) "Nice prank, Simpson. I dare you to dump that bees' nest on those second-grade babies.
Bart: Why would I want to?
Jimbo: Because I said 'I dare you.' Kearney, can you read it back? Kearney, reading: Nice prank, Simpson. I dare you to....."
Jimbo: The point is, Simpson, a dare has been placed on your nards.
Bart: My nards accept.

(Lisa's bees are swarming around the breakfast table)
Bart: Mom, maybe you shouldn't have put so much syrup on the pancakes.
Homer: The secret is not to swallow the stingers. (takes big bite of pancakes with bees on them, and spits stingers out into a glass)
Lisa: Dad, don't eat the bees!
Homer: They're just drones, Lisa, they only live for, like, five minutes anyway! And they only have haploid cells, not diploid like me and Bart!
Bart: Yeah! (high-fives Homer)

Moe: Listen, Homer: in the back room, I got these super-tough Africanized bees. I saw this ad in a gentleman's magazine for excited African honeys and that's what they sent me. If we could combine them with Lisa's bees, it would make them strong enough to survive any environment.
Homer: But how are we supposed to combine the DNA of two strains of the same species?
Moe: Actually, Homer... (whispers)
Homer: (gasps) You and me?
Moe: No, the bees!
Homer: Oh, yeah, yeah, that's what I meant too. I... have no... inclination.

This episode's title is an obvious reference to 'The Birds and the Bees', the euphemism for having sex
