Two dimensional characters fill Houseguest with simple lessons and silly humor.
Kevin Franklin (Sinbad) poses as Gary Young's (Phil Hartman) school boy buddy who is a world renowned dentist. Franklin is on the run from henchmen of a loan shark to whom he owes $50,000. Franklin has been a dreamer since his childhood days in an orphanage. He wants to be wealthy.
When he arrives at Young's home, he is treated as a Houseguest in an upper middle class, very comfortable home. The kids have mild problems and Young and his wife are more concerned about work than the kids' needs. Sinbad cuts up taking silly actions to cover his identity. He even pulls some teeth by accident.
There are few laughs and some very simple lessons learned by the kids and adults alike. This is nothing great, but it's not terrible either.
