Corrected entry: Season 3, Episode 11 "Raising Shane" - A little over halfway through, Dr. Peyton Driscoll tells Detective Mac Taylor their relationship will not work if they're both working in the same lab. During their discussion Mac calls Peyton "Claire", the actress's real name. He says, "That's not true Claire" and then quickly calls her "Peyton".

Correction: While he does use the name "Claire", it's not referring to Claire Forlani. Claire is Mac's wife, who died on 9/11. Even though he is involved with Peyton, this Freudian slip shows how much Mac still cares about Claire.
