One of the game dollar decorations included as part of the Yard Sale is the Laramie Vending Machine. At a price of $3500 it boosts your vanity rating and  gives you 500XP on placement (depending on your bonus multiplier).

Apart from Mrs. Krabappel constantly smoking, the episode reference for this is probably “A Tree Grows in Springfield“. While the Vending Machine didn’t feature in the story, the episode was followed by “Logomania“, a King Kong parody featuring lots of advertising characters and brands from the series. If you missed it, or live in a part of the world where it hasn’t shown yet, you can take a look at this video from the ANIMATION on FOX YouTube channel:
