broadcast of episode #1.04 "Lucy Thinks Ricky Is  Trying To Murder Her" on the 13th November 1952 featured a new opening  "Flashback" sequence which ran for just over a minute and a half. The  sequence involves Lucy telling Ricky that instead of watching TV, they will  read a murder mystery. Then Desi reminds Lucy what happened the last time she  read a murder mystery. This leads into the opening scene of "Lucy Thinks  Ricky Is Trying To Murder Her". This flashback scene has been restored for  the 2002 DVD release of "I Love Lucy".
