Blossom - Season 4 - Eps 25: Seven Deadly Sins
Two aliens in a flying saucer (voices of Joey Lawrence and Michael Stoyanov) choose the Russo home as the site for their observations of earthling behavior, particularly their susceptibility to the seven deadly sins, which are illustrated in encounters between the various characters. (This being a family sit-com, sloth gets the most airtime.)

Synopsis
Blossom Russo is a highly intelligent and spunky teenager.

Along for the ride is Blossom's ditzy best friend, Six, who sometimes shows flashes of great perception.
