History Recap / TheGrimAdventuresOfBillyAndMandyS2E4

** Mrs. Doolin says that Grim never forgave her for beating him at everything. Turns out, she really did mean ''everything.'' She found a way to beat Death itself.

After excluding Mandy from their board game “Who Killed Who?” for being a girl, Billy and Irwin mistakenly throw their dice into the backyard of a haunted house. Grim warns them about the ghost of Mrs. Doolin, a lady that lived there.

** When Mandy disbelieves Billy and Irwin’s claim that Mrs. Doolin’s house is haunted, Grim responds that it is. When Mandy asks him how he knows this, he replies, “Oh, I ''know'', Mandy. I know ''everything'' there is to know about that house.” It’s mainly the bitterness in his voice that hints at the long history he has with Mrs. Doolin.

* GirlsVsBoysPlot: Downplayed. The reason the plot gets set into motion is because Billy and Irwin won’t let Mandy join in their board game for the simple reason that she’s a girl.

* NightmareSequence: Billy has one about how he seemingly left Mandy at the mercy of Mrs. Doolin’s ghost.
* {{Retcon}}: In "Meet the Reaper", when Mandy challenges Grim to a game, he brags that he never loses. This episode proves that to not be the case, as Mrs. Doolin has beaten him multiple times.
* TheReveal: Billy and Mandy weren’t the first ones to beat Grim in a challenge. Mrs. Doolin had beaten him in ''everything'', and as a result, beaten Death. Oh, and she really was a ghost.
* TheRival: Mrs. Doolin is this to Grim, having beaten him in “just about everything”.

** The episode’s title could be seen as a reference to the [[WesternAnimation/TexAveryMGMCartoons Tex Avery MGM Cartoon]] [[WesternAnimation/WhoKilledWho of the same name]].
* WhamShot: The entire ending scene. After Mandy and Mrs. Doolin scare Billy, Mandy looks back inside the house to find Mrs. Doolin gone and the place looking like it’s been abandoned for decades. Mandy walks in and once again looks at the portrait of Mrs. Doolin, but now there’s a mirror behind her that wasn’t there before. And in the mirror’s reflection, [[DeathGlare glaring]] at Mrs. Doolin... is ''Grim''.
-->'''Mrs. Doolin:''' (''voiceover'') Ha! He’s never forgiven me for beating him, in just about everything!\\

After Grim fails to pull a werewolf out of his hat, Irwin is bitten by said werewolf. Then, Billy takes Irwin as his new pet dog, he asks his mother if he can keep the "puppy," but she refuses. Billy asks his father if he can keep the so called puppy. His father, not paying attention, says yes. Billy names the "dog" Sprinkles, and enters him in the Endsville Dog Show to compete against Mandy's dog, Saliva. At the contest, Sprinkles is about to win, so Grim releases a "were-flea" whose bite causes the werewolf to revert to a naked Irwin. In the end, it appears that Irwin won the contest anyway.

When Mandy disbelieves Billy and Irwin’s claim that Mrs. Doolin’s house is haunted, Grim responds that it is. When Mandy asks him how he knows this, he replies, “Oh, I ''know'', Mandy. I know ''everything'' there is to know about that house.” It’s mainly the bitterness in his voice that hints at the long history he has with Mrs. Doolin.

* {{Foreshadowing}}: When Mandy disbelieves Billy and Irwin’s claim that Mrs. Doolin’s house is haunted, Grim responds that it is. When Mandy asks him how he knows this, he replies, “Oh, I ''know'', Mandy. I know ''everything'' there is to know about that house.” It’s mainly the bitterness in his voice that hints at the long history he has with Mrs. Doolin.

'''Mandy:''' ''Everything''!

* ThrowTheDogABone: Near literal example. Even after Irwin is turned back to normal following winning the Dog Show as a werewolf, he's allowed to keep the winning title.
