WASHINGTON (AP) _ It was, in President Bush's words, ''a very special Tuna evening at the White House.''

Tuna, Texas, that is - as performed by actors and quick-change artists Joe Sears and Jayston Williams, creators of two satirical plays about life in the third smallest town in Texas.

Sears and Williams provided the entertainment Sunday night at Bush's state dinner for the governors. The duo performed four scenes and six characters, including three from their ''Greater Tuna'' and ''A Christmas Tuna'' plays and one skit ordered up for the occasion: a phone-call to the White House from Tuna Tastee Kreme waitress Helen Bedd.

The governors and their spouses and Bush and his wife Barbara laughed riotously at the Tuna reprise in the East Room.

Sears and Williams, famed for jumping in and out of dresses, wigs and a myriad of characters, caught the president's fancy Jan. 6 when the Bushes saw ''A Christmas Tuna'' at the Kennedy Center on their 45th wedding anniversary.

A laughing Bush told the audience afterwards, ''Some of you all may have seen these two artists ... in the greatest sense of the word over at the Kennedy Center.

''Barbara and I went a while back, had our kids with us, and I don't think we ever enjoyed an evening more,'' said the president.

He thanked the pair ''for this very special Tuna evening at the White House.''

Afterwards, the actors had one more quick change to perform: out of their Christmas red-and-green satin Tuna robes and into tuxedos to join the Bushes and the governors for champagne and music on the State Floor.
