Quote from Martin in Ain't Nobody's Business If I Do
Sherry: You know, that is so weird. I just got a message from my manager down at McGinty's. Some guy came in asking a lot of questions about me. Martin: What kind of questions? Sherry: Well, like where I used to work, the people I used to date, and the weirdest part is, my neighbor told me somebody came around asking her about me, too. Martin: Sounds like somebody's checking up on ya'. Sherry: You mean like a detective? Martin: Oh no, it's probably a credit card company. Something like that, I wouldn't worry about it. Sherry: Well, still, it is a little scary. I wish I knew who it was. Martin: Oh, forget it, honey. I've been through this before. Private investigators never leave a trail. Really, it could be anyone. [As Sherry goes to the kitchen, Martin gets up and walks over to Frasier and Niles] Sherry: If you say so. Martin: Which one of you hired him?
