That's So Raven - Season 4 Episode 19 -

Raven is getting very annoyed with Donna Cabonna because she wants to be a fashion designer, not a maid. Then, Donna's ex-best friend (but now arch-enemy), Lora Stelladora, moves into the office upstairs, and offers Raven a job as a fashion designer. Raven quickly finds that she has to deal with two bosses. Meanwhile, Cory and Eddie try to profit on Chelsea's potato that resembles Abraham Lincoln.
