Chicago–Melvyn I. Weiss had a frog in his throat that he could not get rid of.

The frog persisted, and he asked for a drink of water as he choked on answers to his own lawyer’s questions about his accomplishments, his three children, his 11 grandchildren. From the witness stand, Mr. Weiss apologized to the jury–five men and five women who could determine the fate of his firm, New York’s Milberg Weiss Bershad Hynes & Lerach L.L.P.
