Cheese Chasers marks the last appearance of Hubie and Bertie from the Classic era. Also featured in this short is a bulldog predecessor to Marc Antony.
Yankee Doodle Daffy was the second Technicolor Looney Tunes entry to feature Porky Pig and Daffy Duck.
The first one was My Favorite Duck (1942).
In the 1988 TV special/compilation Bugs vs. Daffy: Battle of the Music Video Stars, Daffy refers to his abrupt transition from banjo playing to Carmen Miranda impersonation from Yankee Doodle Daffy as his "crossover hit, 'Banjo Chicky-Boom.'"
Bulldog (To Claude the Cat): You're a cat, right?
Bulldog: And cats eat mice, right?
Claude (Shaking his head): No!
Bulldog (Confused, looking at Hubie and Bertie): And you two... you're mice, right? (The mice nod) And mice, they eat cheese, right?
Hubie and Bertie: Cheese! Yaaaaah! Don't mention that word!
Hubie: Hey, Bert.
Bertie: Yeah-yeah, Hubie. What is it, huh? What is it?
Hubie: Let's quit.
Bertie: Yeah-yeah, sure-sure. I don't feel so good.
Hubie: Bert, an average mouse eats 12 pounds of cheese in its lifetime. I figure tonight we've lived 2,000 years.
Bertie: Hubie, I'll never be able to touch the stuff again.
Hubie: Me neither. So there's nothing left to live for.
Bertie: You mean?!
Hubie (Nods): Come on, Bert, let's get it over with.
Bertie: Yeah yeah. Over. (Hiccups)
Bugs Bunny: You realize that this is not going to be unchallenged.
Sleepy LaGoon (Baritone singing): Let spring-time blossoms bloom again... Of... (starts coughing loudly) ... m-my heart.
Daffy Duck: Yes sir, Daffy Duck! Personal representative of the most sensational discovery since the Sweater Girl! He's colossal, he's stupendous! One might even go so far as to say...he's mediocre!
Cheese Chasers can be seen (uncut and restored) on the second volume of The Looney Tunes Golden Collection DVD set.
When Cheese Chasers aired on The WB, the part where Hubie and Bertie hit Claude's foot with a hammer in an attempt to be eaten by him was cut.
Cheese Chasers is 7 minutes long.
Cheese Chasers was released on August 25, 1951.
On Cartoon Network's edited version of Barbary Coast Bunny (which only aired once in 2004 and was shown uncut years prior), the entire ending was replaced with a repeat shot of Nasty Canasta's face after Bugs beats him at poker intercut with Bugs carrying his winnings in a wheelbarrow.
On "The Merrie Melodies Show," the part from Barbary Coast Bunny where Nasty Canasta spins the gun chamber and aims the gun at his face is shown, but the gun blast is replaced with a frozen shot of Bugs's face.
The CBS version of Barbary Coast Bunny keeps in Bugs winning the gold from Canasta's gun, cuts out Canasta doing the same and getting shot, and resumes at the part with Bugs' "18 karats" line.
Barbary Coast Bunny was released on 1956.
Yankee Doodle Daffy is the first cartoon in the collection that came from public domain.
Yankee Doodle Daffy is 6 minutes 43 seconds long.
Yankee Doodle Daffy was released on June 5, 1943.
