Continuity: When Melvin gets up to go give Simon some Chinese soup, the clock reads 3:22am. The next scene in Carol's apartment is supposedly later on the same night, yet the babysitter has just arrived, her child is still up, and she and her mom are getting ready to go out for the night (even telling the babysitter that there's pizza in the freezer they can cook later). We know it is supposed to be the same night because in the ensuing scene, Frank tells Melvin he heard he "brought Simon chicken soup last night."

Continuity: When Melvin goes to the restaurant after seeing the psychiatrist and is not served by Carol he bangs on the table and tells the waitress to go and get her. The flowers in the vase on the table change twice in consecutive shots. Pre-bang = yellow, orange and red. Post-bang 1 = white, 2 yellow and red. Post-bang 2 = 2 white and 2 yellow.

Continuity: When we see Carol writing the thankyou note, the page is numbered (23), there are 8 lines of writing on the page and she says she is on the last page. When she is looking up the word 'conscience' in the dictionary, the paper is visible again but it is a different sheet - there is no number and there are only 4 lines of writing. It is the page she is about to write on because the last words written are 'have it on my ' - 'conscience' following this phrase makes sense.

Continuity: In the first diner scene Melvin sits down and takes off his glasses. He starts fiddling with the button of his breast pocket. When the camera angle changes his hands are somewhere else and the pocket is still buttoned. When it changes again he is putting his glasses into the now unbuttoned pocket.
