Jetta: I guess a homemade party can be lots of fun.
Mr. Howard: I've got to hand it to you, Emily Elizabeth. You and Charley really made this party special.
Mac: Jetta's not going to any party.
Clifford: She's not?
Mac: No. She's moping around in the house with nothing to do.
Mary: Happy birthday, Emily.
Emily Elizabeth: Thanks, Mary!
Emily Elizabeth: Okay, Clifford. We'll skip Jetta's house.
Jetta: Here comes Emily Elizabeth to invite me to her boring old party. Oh well, I have nothing better to do that day.
Jetta: You know what makes a party fun. Sparkle! Excitement! Pizazz!
Mr. Howard: I think it's wonderful that you two are making all these things for your party by yourself.
Emily Elizabeth: We're off to search for a great white whale. (sees Clifford) Make that a great red whale.
Emily Elizabeth: This is going to be the best birthday party I ever had.
Emily Elizabeth: At least there was one friend who never doubted me. The most loyal friend I could ever have: Clifford.
Clifford: Someone's taking things that don't belong to them and I'm going to catch them.
Emily Elizabeth: I'm sorry we didn't find your medal.
Jetta: My neck is just so bare without it.
Emily Elizabeth: I would never take your medal.
Jetta: You were jealous because I won the spelling contest, so you stole it.
T-Bone: What a great bone!
Clifford: Yeah. I wish Cleo was here to help us chew it up.
Cleo: Hiya guys!
T-Bone: How'd ya' do that, Clifford?
Jetta: No, Mac. No tummy-yummies in there. Just my shiny, new medal. Hmm... Oh! My medal! It's gone! And I bet I know who took it.
Ms. Carrington: Emily Elizabeth, spell the word "monkey."
Emily Elizabeth: "Monkey." M-O-N-K-E-E. "Monkey."
Ms. Carrington: Ooh, I'm sorry. That's incorrect.
This is the first episode to break the trend of only three Speckle stories.
The number of candles on Emily Elizabeth's cake in "The Best Party Ever" is nine.
"The Best Party Ever" marks the first time Mary, the girl in Emily Elizabeth's class in a wheelchair, has a speaking part. It's also one of only two or three Clifford stories in which Mary's name is mentioned. Mary is voiced by Kath Soucie, who also does the voice of Jetta. This credit isn't given on the episodes aired on TV, but is shown on some of the Clifford DVDs in which Mary has a speaking role.
