Plot summary
Lois and Clark's wedding is only few days away and Lois worries that something bad will happen. While they are trying to make everything work, Lois asks Perry to give them a story so she can get her mind away for a while. Perry gives them a story about some frogs that have been stolen from a pet shop but as it is revealed soon, this is not just a frog robbery. Their investigation leads them to discover that a scientist named Dr. Isaac Mamba ( Tony Curtis ), who used to work for Lex Luthor, replaced the President of the US, President Garner ( Fred Willard ) and one of his Secret Service agents with frog-eating clones that he has created.
Lois and Clark solve the mystery and Mamba, along with the clones, get arrested while Lex escapes from prison after an official pardon that was written by the president clone. Lois and Clark get married but at the end of the episode it's revealed that the Lois who is with Clark is also a clone as the real Lois was replaced before the wedding. Note: The episode is dedicated to the memory of Superman co-creator Jerry Siegel, who died on January 28, 1996.
