Tweety Bird solemnly swears

Tweety Bird may get a chance to take the witness stand and sing like a canary.

An Italian court ordered the animated bird, along with Mickey Mouse, Donald Duck and his girlfriend, Daisy, to testify in a counterfeiting case.

In what lawyers believe was a clerical error worthy of a Looney Tunes cartoon, a court in Naples sent a summons to the characters ordering them to appear Friday in a trial in the southern Italian city, officials said.

The court summons cites Titti, Paperino, Paperina, Topolino -- the Italian names for the characters -- as damaged parties in the criminal trial of a Chinese man accused of counterfeiting products of Disney and Warner Bros. Instead of naming only the companies and their legal representatives, clerks also wrote in the witness list the names of the cartoons that decorated the toys and gadgets the man had reproduced.

“Unfortunately, they cannot show up, as they are residents of Disneyland,” quipped Fiorenza Sorotto, vice president of Disney Co. Italia.
