Craig Ferguson loves himself a good theme week -- Magic Week and Paris Week were previously my favorites, but this new Celebrity Geoff initiative is quickly eclipsing both of those since it combines two of my favorite things: robotic skeletons and famous voices!

The "Guess Who?" game has been going on since November 7 with stars like Dominic Monaghan, Alfred Molina and Larry King providing the vocal stylings for Craig's sidekick.

"I'm just glad so many people are willing to work for nothing," Craig joked. My favorite guest star grabbed the mic this week as Geoff kicked it cross-dressing style -- can you guess which lovely lady is supplying the voice?

The Late, Late Show with Craig Ferguson airs weeknights at 12:37 p.m.on CBS.
