Corrected entry: When Carla asks Frasier if he's "taken a good look at everyone else", the camera pans to the bar patrons. Dianne is sitting at the bar smiling. She wouldn't be drinking at Cheers because of her recent falling out with Sam. Dianne then comes in the bar looking for Frasier a minute later wearing different clothing. (00:06:50)
Corrected entry: Sam's friend Eddie shows up and says they made a bet a year ago while drinking tequila. This isn't possible, prior to his "falling off the wagon" when Diane left he hadn't had a drink in about five years (he told Diane 3 years in the pilot episode) and a year hadn't passed since he's fallen off the wagon when Diane left.
Revealing mistake: When Frasier comes into the chalet after skiing he doesn't show any of the visible effects after a hard day on the slopes. Meaning, his face isn't even flushed from the cold, his hair is perfectly combed after wearing a hat and there is not even a drop of snow on his boots.Tobin OReilly
