Psych S02 E08 Rob-a-Bye Baby

"Fake psychic. Real detectives."

Shawn and Gus want to be put on Lassiter's burglary case, but a sleep-deprived Chief Vick orders them to find her a nanny instead. Unfortunately, at least from Lassiter's view, the two teams keep crossing paths, and Shawn sees an opportunity to horn in on the more interesting case.
