When Spanky feeds Bumbo just about everything in the icebox, one of the items he pulls out is a portion of a roll of bologna, cut in the middle so that the last two large letters of the brand name "Luer", are seen at the sliced end. He hands it to Bumbo and when he takes a bite, the bologna is longer, and the letters UER are now visible. (Luer's was a popular brand of hot dogs and luncheon meats beginning in 1885 in Los Angeles, and continuing at least into the 1950s when the company's "Quality Meat" rocket ship vehicle - similar to the Oscar Mayer 'Weinermobile" - travelled the United States promoting its products.)
During the ice box scene Spanky gives Bumbo the sardines, wieners, bologna, then a whole bowl of raw eggs that Bumbo eats shell and all. Then Spanky gives him Tabasco, vinegar, mustard and a gallon of port wine which Bumbo drinks without stopping. The camera cuts back to the amazed Spanky which shows the bowl of eggs full again.
