John Stamos stopped by to help Harry with a special Bat Mitzvah message for Harry's niece Emily.
Harry told John Stamos his family is putting together a montage for Emily's birthday and asked him to record a special message for her.
In the first version Stamos said, "Hi Emily this is John Stamos from Full House, Fuller House an Grandfather and I’d just like to say congratulations on your Bat Mitzvah and I wish you the best."
However, Harry said the video needed "a little more soul" so John decided to try again.
