If you were given the chance to switch the roles of the characters, which ones would you switch?

Example:
Jack could be Larry
Larry could be Mr. Furley
Mr. Furley could be Jack
Janet could be Lana
Lana could be Mrs. Roper
Mrs. Roper could be Chrissy
Chrissy could be Janet

That Mr. Roper and Mr. Furley would switch roles....... LOL
