Beaver is concerned about his freckles, so he asks his father about them. Ward tells Beaver about a freckle-faced kid in the old "Our Gang" comedies who always got laughs and was laughed at when he came on screen. Ward never mentions the freckle-faced boy's name, but he is obviously speaking about Mickey Daniels.
The "Our Gang" short that Ward speaks about with a freckle contest is real. A Pleasant Journey (1923), which is in the public domain, includes a freckle contest just after the 3:00 mark.
Ward says that Abraham Lincoln was president and everyone loved him. This is obviously not true. Almost immediately after Lincoln was elected president, 11 southern states secede from the Union to start their own county, The Confederate States of America.
