4x19 - Get Smart

The Chief takes up computer dating and winds up dating a gorgeous young woman. The Chief's boss (unseen) orders Max and 99 to follow the Chief to make sure that this romance is not a security risk. 99 also thinks that the Chief should be dating someone more his age, like her mother. The young woman is actually the wife of Dr. Paponickolini, who is giving the Chief a secret formula for eternal youth. The Chief arrives at Max's apartment for a dinner date with 99's mom but instead KAOS shows up and kidnaps 99's mother, thinking she's the wife of Dr. Paonickolini.
