Episode 111: "The Black Tie Affair"
Later, at the Love Train Diner, Danny and Floyd both express their concern about Linda dating Marty. Floyd is concerned about Marty, a health department inspector, being around the diner all the time, and Danny feels the need to protect his mother from dating and having her heart broken again.
On the night of the Mayor's Ball, Danny solicits Floyd and Sam's help to check out Linda's new man. In an attempt to interrogate Marty, they wind up telling him made-up stories about Linda and her nonexistent past of dating men in prison, seemingly scaring him off. When Linda comes downstairs looking for Marty and hears what has just happened, she is devastated.
Danny and Linda have a heart-to-heart. He explains that he's protective of his mother because he doesn't want her to fall in love too quickly again. However, Linda lovingly reassures him that her past bad relationships have actually made her stronger.
Ultimately, Marty, not to be outsmarted, refuses to fall for Danny and Floyd's embellished stories and returns for Linda, whisking her off to the Mayor's Ball.
