Mauricio Borensztein (27 April 1927 – 11 January 1996), known by the stage name Tato Bores, was an Argentine film, theatre and television comedian, who specialized in political humor.

When in character, he wore dress coat, white bow tie and a deliberately badly cut wig, and waved a cigar.

In one of these, he appeared as Dr. Helmut Strasse, "argentinologist", an archeologist specialized in the lost land of Argentina, which had sunk into the Atlantic Ocean 500 years before the fictional time frame of the show.

Before the broadcast of one of the programmes, federal judge María Servini de Cubría was warned that the show contained an ironic comment about a ridiculously low fine she had received for mishandling a case.

Borensztein received overwhelming support from the artistic community of Argentina, but respected the judicial order, from then on referring to the judge as "the unnameable" or as Jueza Barubudubudía (intended as a nonsensical yet transparent rhyme of "Servini de Cubría") until the censorship was lifted.
