However, there are other cartoons with two cavemen:
* The Croods is a movie about a family of cavemen, with the main characters being Grug and Eep.
* The Bugaloos is a cartoon featuring cavemen with a band called the Bugaloos.
* The Mighty B! features a character named "Caveman Bob" as the father of the main character, Bessie.
If you can remember any other details about the cartoon, like the setting or the characters' names, it might help narrow it down!
