Lisa's crush on an environmentalist (voiced by Joshua Jackson, who was on Dawson's Creek at the time) leads her to camp out on Springfield's tallest tree in protest over plans to have it felled. Meanwhile, Bart gets a job as a menu delivery boy for a Thai restaurant so he can raise money for a new video game system.
"Lisa the Tree Hugger" contains examples of:
- Bait-and-Switch: When Bart asks for money to buy the new vídeo game system, Marge says she'll help him... by singing a cheesy song about being thrifty.
- Bland-Name Product: The game system that Bart is trying to get is the latest GameStation.
- Card-Carrying Villain: Rich Texan.
- His company's corporate headquarters has a painting of a steamroller happily crushing a scared flower.
- When the log crushes Hemp City, he celebrates and declares it a point for the bad guys.
- When Lisa asks him if he has no shame, not only does he says he doesn't, he points to his Rolls-Royce (which has trapped a poor beaver's tail when he parked on it), which literally has as its Vanity License Plate "NO SHAME".
- Halfway Plot Switch: The plot of Bart getting a job to earn money for a new video game console sudden switches to Lisa's plot once the Simpsons discover Dirt First on the roof of Krusty Burger.
- Karma Houdini: Despite Marge's worry, Lisa and her family don't get in trouble for lying about her death.
- Last Request: When Lisa was mistaken for dead, Homer took advantage of this to make Moe believe it was her dying wish that he poured his egg jar's contents down his pants and ripped Homer's tab.Lisa: (on tape) Dad, I can't—
Homer: (on tape) Read it!
- Off-Model: Check out some of the characters in the background of the shot when the Rich Texan addresses the crowd. Particularly Lenny (with his extra long lips) and Apu and Largo (who have huge pupils).
- Totally Radical: The GameStation 252 when Bart wants to upgrade to a 256.
- Trees into Toothpicks: The logging rights for the Oldest Redwood in Springfield are sold for $100,000 to make a drive-through humidor. One of the other bidders is the restaurateur Bart was working for, who wants to turn it into Thai takeout menus.
- What Happened to the Mouse?: Bart's storyline about raising money for a new video game system seemed to disappear after Bart is trained Matrix-style in leaving menus behind. It gets two more acknowledgements (the Thai restaurateur bidding for logging rights on the redwood, and Bart's care package including food from the restaurant), but it's never explained if he got his console or why he left a decently-paying job he liked.
