"Tino Tonitini (Jason Marsden) functions as an interlocutor between the show and the audience. […] He’s emotionally insecure despite his obvious intelligence and his sly, ever adept wit (he’s one of the very few television animation characters who can be funny only through his words). His perceived failings, though heightened by personal exaggeration, are displayed to the audience chiefly because he is the focus of most of the stories, with his friends good-naturedly mocking his neurotic and "weird" behavior. In most episodes, Tino paints himself into a social or emotional corner that he fears will ultimately overwhelm him (in one memorable instance, he confronted his fear of clowns). He’s able to work through the situation with the aid of his three close friends, as well as his sensitive and understanding divorced mother (voiced by Lisa Kaplan), whose obsession with vegetarian cooking provided the series with one of its surprisingly large collection of subtly stated, interlocking running gags."
