SMELL FISHY
Sally witnessed something really strange in the office this morning:
PETER: What's wrong, Sally?
SALLY: Oh, Peter. I don't know how I can tell you that...
PETER: Tell me what?
SALLY: I saw Michael and Ms. Moore together in her office.
PETER: So what?
SALLY: He was hugging her in a different way...you know.
PETER: Hummm....It smells fishy to me.
If something SMELLS FISHY TO YOU, it seems suspicious. They are probably thinking that Michael is having an affair with their boss.
