There's a few times where Psych mentions the Mentalist and makes a small joke about how both shows are very similar (i could make more than a few similarities). But one of the cool things I've noticed is that they share an actor. In ghe first episode of the sixth season, Shawn and Gus help some English diplomats and the older English diplomat was played by Malcom McDowell, who played an occasional role of Bret Stiles in the Mentalist.
