Continuity mistake: Laura Dayton is at a party at the Ponderosa but leaves and goes outside because she has a headache. Ben Cartwright's brother Will comes out and says he'll take her home via horse and buggy. It is night and the sky is dark, but when they reach Laura's house, it appears to be early evening. The sky is much lighter and the trees are casting long shadows on the ground.
Continuity mistake: Adam and Joe are restraining Hoss while Ben gives him a ladleful of a thick white tonic for "spring fever." Joe has his right arm around Hoss' neck and is holding Hoss' mouth open with his left hand. As Hoss takes the tonic, a glob of it spills onto his left cheek. In the immediate close-up, the glob has vanished.
