Peggy mentions that she is no longer subbing at Tom Landry Middle School. It is unknown why she isn't, since in previous episodes, she wasn't neither fired, nor she wasn't seen quiting.
It may due to the fact that Fox/censorship doesn't allow it, but if Lucky was really as injured as was said, his bandage would have blood on it.
Tagline: "Have a socially relevant day." -Bobby
Luanne: Aunt Peggy, I just swallowed a watermelon seed! What if it grows into the baby? I don't want a watermelon baby!
Lucky: Luanne, we talked about this. We're gonna love that baby no matter what.
Minh (as Bobby is giving a speech about oppression in lieu of the carnival he is supposed to be throwing)
: You thought your son was unpopular before? Peggy Hill, prepare to be his prom date.
Bobby (as he is feeling guilty from his ancestors' transgressions, and talking with Joseph about it): Look at that snowcone machine. First, we took the Eskimo's land, and now we're gonna eat it!!?
Joseph: How do you think I feel? As a white man, I've killed a little bit of everybody!
Dale: I met Nancy at the kissing booth of a carnival. Even with 200 boys lips there, that kiss was magical.
Diversity Instructor: Look at those kids – a powder keg of diversity!
(The students are brainstorming ways to bring attention to intolerance)
Joseph: I wish I could tape their eyes open and shove their faces into the truth!!
Bobby: School is so boring. We need a fire alarm or a good class vomiting to mix things up.
Peggy: Too bad I'm not subbing there anymore - I was the fun teacher! Do the kids still talk about the day I brought in microwave popcorn?
Lucky: Sorry, but I don't do hospitals. Everyone I know that's died has been shot in the woods and then taken to the hospital... where they died. No hospital!
Boy: "I hear the new girl is really 22 and secretly a cop."
This is very similar to the plot of the movie Never Been Kissed (1999). In it, Drew Barrymore plays a 20-something journalist who tries to go undercover as a high school student to get inside their world, while everyone else pretends she really looks like a high school student.
Diversity Leader: Some of you will have to wear stars on your person at all time.
The Nazis did this to distinguish Jewish people from others in ghettos and at concentration camps during World War II. They also made other 'undesirable' groups wear indicative symbols.
Clark Peters: "I'm a policeman? Ugh, I'm getting too old for this crap."
This is a reference to the Lethal Weapon movies. Danny Glover's character, Roger Murtaugh, says, "I'm too old for this s***," or other versions of the same line, throughout the 4 movies.
The title of this episode is a play on "The Tears of a Clown", a 1967 song by Smokey Robinson and the Miracles.
