For the record, Kim Caldwell and Ruben Studdard guest starred together in the SAME episode of "Life On A Stick." It aired 3-4 years ago. They played two of the employees at an ice cream stand that is opening in the same mall that our heroes (?) work in, and they were hoping to run them out of business. Ruben has virtually no dialogue-- maybe Kim copped all of his lines. She gets to give the finger to the show's heroine and is perfectly convincing as a total bitch. Okay, so it's not a stretch, but remember--the worst actors can't even play THEMSELVES convincingly.
