The population of Cactus Corners starts out at 1864 but the gunfights rapidly decrease the number to 930. This must have overwhelmed the undertaker, Berry M. Deep.
Popeye arrives by horseback while sitting in a sailboat. This is a play on the term prairie schooner, which transported thousands across the American continent in wagon trains.
As Popeye rides into town, he passes some graves with wooden markers indicating who's buried in them. The first is Sheriff Peg-Leg, who "Died Mon. - 9", and the mound of dirt is missing a section that would correspond to a person's right leg if he were buried facing up. The second is Sheriff Slim ("Died Tues 10"), and his grave's mound of dirt is very narrow. The third gave marker shows that Sheriff Shorty "Died Wed. - 11", and his grave (of course) is much shorter than the other two.
When Wild Bill Bluto "slingshots" Sheriff Popeye to his "last round-up" in the open grave (next to Sheriff Shorty), the wooden marker that originally said "Sheriff wanted to fill this opening" changes, after the dirt piles on top of Popeye, to "Sheriff - Popeye - Retired Saturday-11th". This indicates that Cactus Corners went an entire month (i.e., 31 days) without a sheriff as Shorty died on the 11th, but on Wednesday.
Just about every Western film cliche is shown here, from the yellow streaked cowards to the melodramatic victim's demise.
