Continuity mistake: Jerry says he has never seen an episode of I Love Lucy in his life, then pops the cork on the wine bottle. Then it cuts to the lady and she asks, "Is there anything else about you I should know?" and the wine bottle is still on the table, corked. Then it cuts back to Jerry, and the bottle is still in his hand uncorked.
Continuity mistake: In the scene which starts with Jerry saying he has never seen an episode of I Love Lucy in his life, two wine glasses switch sides. The one with wine in it is on the left side of the screen, then 5 seconds later it is on the right side. Jerry also takes the cork out of the wine bottle and then in the next shot it is back on, only for the next shot for it to be off again.
