The New Adventures of Old Christine: The Real Thing

Christine gets Mr. Harris and herself in trouble with the school when she accidentally sends a suggestive email to all the parents and Mr. Harris instead of to Barb as she intended. When Mr. Harris tells Christine he is dating someone, Richard convinces Christine to go out with his friend Tom. While she's out on her date, she runs into Mr. Harris who is at the same restaurant with his date. While Tom is in the restroom with stomach problems, Christine and Mr. Harris chat and Mr. Harris reveals that he's only dating this woman so he won't think about Christine.
