Billionaire investor Warren Buffett will be drawn into a fictional insider-trading scandal in an upcoming appearance on the TV soap opera "All My Children."

Buffett, 77, will play himself in an episode set to air during the May "sweeps" ratings period. It will be his second guest turn on the ABC daytime drama, a show spokesman said on Wednesday. His first appearance was in 1992.

Buffett and the creator of "All My Children," Agnes Nixon, are friends, and the investment magnate is a fan of the show, said the spokesman, Mike Cohen.

"He's been waiting for an invitation to come back, and he was speaking to Agnes, and they made it happen," Cohen told Reuters.
