Max: When the moon is full, the tide is high.
Old Lady: You must want the spy school, that's next door.
When Max is phoning the Chief to let him know the mission's been accomplished, he takes the oars out of the oarlocks before opening his shoephone. The oars change from being out of the oarlocks in the closeups to still being in the water in the long shots for the rest of the episode.
After Max sinks 3 balls with one shot, The Shark says "I haven't seen anyone make that shot since the great Three-Fingers Yarmy." Don Adams' birth name was Don Yarmy. (He took his wife's last name for show business).
