Funny / More & More & More Tales to Give You Goosebumps

• The entirety of A Holly Jolly Holiday is hilarious, especially the main premise. It's about a girl whose older sister loves a completely sappy and corny Christmas special, and manages to find a video tape of it at the mall. But the video magically transforms the viewers into the movie's main character, Susie Snowflake, and the girl is horrified as her parents, sister, and even her dog turn into redheaded baking-obsessed idiots. In fact, it starts happening to the girl as well, who mentions she tried to swear at one point but could only say "Oh sugar cookies!"
• As mentioned by Blogger Beware, the ending of Marshmallow Surprise can be considered one. Basically the story builds up to a climax where Mrs. Spooner reveals that Marsha and her brothers are going to melt into goo as revenge for the pranks they've pulled on her, and then out of nowhere the kids turn out to be werewolves and eat her. It's so completely stupid it's hilarious.
