While dinning with "Selena" and her father John Boy is having trouble trying to figure out how to eat his lobster. In fact he remarks "aren't there times when you just have to admit your licked" and gives up trying to eat it and asks for rolls. But in a previous episode Season 2, episode 1, he seems to have no trouble dismantling one when dinning with the elderly lady "Maggie". Or at least that is what a close up shot of his dinner plate shows.
After Selena's grandfather excuses himself to retire for the night the big clock says nine thirty. John Boy and Selena have a discussion sprinkled with kisses which takes at least 5 minutes yet the clock still says nine thirty as Selena shows him the door.
