Frank Gorshin on Lois & Clark

Frank Gorshin (1933-2005) was an actor and impressionist who gained TV fame as special guest villain the Riddler on TV's Batman in the 1960s.

In the second season Lois & Clark: The New Adventures of Superman episode "Whine Whine Whine," he made a cameo appearance as one of the three sleazy lawyers consulted by Superman. Gorshin's lawyer character rants, gnashes his teeth, and talks about how he always goes in for the kill (before leaving for his yoga session).
