* CrossOver: The comic strip ''ComicStrip/HiAndLois'' exists in the same universe as ''Beetle Bailey'' (both originally done by Mort Walker). Beetle is Lois' brother. To celebrate the 40th anniversary of ''Hi and Lois'' in 1994, they had Beetle visit them on furlough.
* ExecutiveMeddling: One strip had General Halftrack demanding a good explaination for why Ms. Buxley was late. He then ogles her after she replies that her bra strap broke. Because of complaints by readers, Mort Walker ended up putting Halftrack through sensitivity training.
** Also, for unknown reasons, a January 2006 strip had censored Rocky's explaination of his past by claiming he sold cars across the street from the junkyard (originally it was across from the parking lot where he stole the cars). It was shown uncensored in Norway, however.
** Japan dropped the series from the ''Stars and Stripes'' magazine during the 1950s because of disrespect to high-ranking military personnel.
* GermansLoveDavidHasselhoff: Beetle Bailey has always had a huge following in Scandinavia, Sweden in particular. This may be due to the fact that Sweden has had full conscription for a long time, making military humor something nearly the entire male population can relate to.
* HeyItsThatVoice: In the animated series, Beetle Bailey's and General Halftrack's voices were provided by Howard Morris, who also did voices for [[WesternAnimation/GarfieldAndFriends Wade Duck]] and [[ArchieComics Jughead]], among others.
* LongRunner: Beetle Bailey originally joined the army during ''the Korean War''.
* [[RecycledScript Recycled Gag]]: There must be dozens over the years, possibly trying to rely on the fact that with the total number of strips being somewhere in the order of the total number of atoms in the universe, no-one would notice. You might find the exact same strip re-drawn years later, or the same gag being used in a single strip and in the middle of a longer "story". Some examples:
** "The training is going well. When we began, they didn't even know [simple thing]. Now, they don't even know [complicated thing]."
** The soldiers are each dreaming about what's typical for them. Beetle is dreaming about sleeping and/or Zero is dreaming a blank thought bubble.
** Sarge and Louise Lugg going out with their pets in tow is called a "double date".
** Sarge goes out to eat alone but asks for a table for several persons because there won't be room for his order otherwise.
** See also under HypocriticalHumor.
* WriteWhatYouKnow: The fact that [[ThePiratesWhoDontDoAnything Camp Swampy's soldiers never go to war]] makes sense if you know that Walker had an uneventful military career as a supply officer during WWII. He was never on the front line.
* WriteWhoYouKnow: Mort Walker claims to have based most of his original cast on people he knew in the miltary.
** He has said that ''both'' Beetle '''and''' Lt. Fuzz were based on himself (he was a 'maverick' who gained a commission while in the army).
** The general was based on one who "couldn't lead a cubscout troop into a candy store."
** Zero is based on a nice guy who tried his best but always ended up bumbling things.
