History ComicStrip / GasolineAlley

* CanonDiscontinuty: This strip is usually very good about keeping maintaining continuity. However, one story in 1995 features Rover's birth mother telling him the back story about his father, which is completely different from the story that was told when these characters were introduced in 1981.

* BizarroEpisode: A few storylines from the 1990s, and many more from the 2000s fall into this category.

* ThoseTwoGuys: Joel and Rufus. Hack and Sarge.

* TheBusCameBack: Rover's biological mother in 1995. Hoogy in 1997. Lil Skinner in 1999. Eve in 2004. Gretchen in 2013. Chipper in 2016.

* ThoseTwoGuys: Joel and Rufus

* LaterInstallmentWeirdness: Throughout the 2000s, the strip seems to have deviated more and more from its long-time premise. For three generations, it was a semi-realistic depiction of small-town family life. Lately, it features a lot more slapstick and/or absurding humor, a heavier focus on characters outside of the Wallet Family, not to mention talking animals.

* BusCrash: Walt's friends Avery, Doc and Bill were phased out as the strip began to focus on Skeezix's family. They were mentioned years later, all having died "off-stage". Happened to Mr. Pert as well.

* Jerkass: Mr. Pert. Wilmer Bobble. The snooty salesman who seems to work in every store Skeezix visits.

* [[Jerkass]]: Mr. Pert. Wilmer Bobble. The snooty salesman who seems to work in every store Skeezix visits.

* MethuselahSyndrome: [[PlotArmor By virtue of being the main character]], Walt at 116 would be the third-oldest living person (and the oldest living man) in the world if he were actually alive, and he's likely not going away anytime soon. The current writer of the strip has stated that he does have plans for this issue; ''what'' plans, however, he isn't saying.
* NotAllowedToGrowUp: Averted. Walt is 116 years old (Phyllis was 105 when she passed away in 2004) and Skeezix is now 94. While some characters have, the most popular and important characters will probably never get around to actually dying, but characters who were young in the RoaringTwenties are ancient now and characters who were introduced as children have families of their own.

'''''Gasoline Alley''''' is a comic strip created by Frank King and currently distributed by Tribune Media Services. First published November 24, 1918, it is the second-longest-running comic strip in the US and has received critical accolades for its influential innovations. In addition to inventive color and page design concepts, King introduced real-time continuity to comic strips by showing his characters as they grew to maturity and aged over generations.
