In the Futurama episode "That Darn Katz," the leader of the hyper-intelligent cats says that when they first came to earth, during the time of the Egyptians, they became domesticated because the Egyptians provided them with "feasts most fancy, and vittles most tender," in reference to Fancy Feast cat food and Tender Vittles.
In the Venture Bros episode "Operation P.R.O.M." Sgt. Hatred states that he got his previous tattoo removed, except for the area over his equatorial region, stating that it's "Tender Vittles down there".
