Double Jeopardy

Plot:

Clark waits for Lois in bed on their wedding night. Instead of finally making love, Lois tells him that she's tired and goes straight to sleep. The disappointed groom can do nothing but also go to sleep. It turns out that the Lois Clark married is a clone while the real Lois is with Lex Luthor, recently granted a pardon with parole from the cloned president from the previous episode. When Lois finally manages to escape Lex, she hits her head and loses her memory.
