If Thursday night's episode of "CSI: Crime Scene Investigation" seems to be funnier than usual, it is because it was written by the writers from "Two and a Half Men" as part of a crossover.
On the "Two and a Half Deaths" episode, Grissom (WILLIAM PETERSEN) and the rest of the CSI team are drawn into the world of Hollywood comedy when a diva sitcom star (played by KATEY SAGAL) is murdered while filming on location in Las Vegas.
Other comedy guest stars include RACHAEL HARRIS ("Notes from the Underbelly"), DIEDRICH BADER ("The Drew Carey Show") and CONSTANCE MARIE ("George Lopez").
"CSI" airs Thursday nights at 9 p.m. on CBS.
