On 30 Rock, Frank Rossitano is a writer for NBC’s TGS show. He’s sarcastic and childish, and all of it comes through in the catchphrases he wears on his hats and shirts.
In That 70’s Show, Bob Pinciotti is Donna’s dim-witted but lovable father. He’s up to date on the latest fads, sporting a permed hairdo and polyester suits. He also likes to lounge around the house in nothing but an open bath robe.
