Guess What’s Coming to Dinner?
Nigel Planter needs help from Grim, Billy, Mandy and Granny Grim to win a girl's heart (whom of which seems to be a spoof of Ginny Weasley, from Harry Potter). Through a series of trials, love potions, spells, and the rivalry between Nigel and Dorko Mouthwad (a spoof of Draco Malfoy) for Herfefiny's heart. In the end, Dorko gets the girl, and Nigel falls in love with his chocolate.

- When Billy was giving Nigel ideas on how to get Herfefiny to like him, he suggests giving her a noogie or throwing a kickball at her, explaining that that's what the boys at his school do when they like a girl.
- Even though Nigel's father was seen, in his next appearance, he's said to be dead.
- It is possible that he is Nigel's adopted father or that he died sometime after this episode.
- This is the last episode to feature Dean Toadblatt with his original design and voice actor.
- It is also the last episode to feature the Squidhat.
- Dean Toadblatt and the Squidhat's wedding marks the only open portrayal of homosexuality in the series.
- However, this is not the first Cartoon Network show to have openly gay romance onscreen. The others are I Am Weasel (Weasel and Baboon's wedding), Courage the Cowardly Dog (Kitty and Bunny), Adventure Time (Princess Bubblegum and Marcie), and Steven Universe.
