 CONT: In episode 1.4 when Lucy and Ricky swap the cups (one contains  sleeping powder Lucy thinks is poison) first Lucys (containing the  powder) is on the right and Rickys is on the left. Lucy swaps them,  so that they are now on the opposite sides. Then Ricky switches them  back, meaning they are back to their original places. Then, Lucy  sips the cup on the left (which was originally Rickys cup and did  not contain the powder). For the rest of the episode we are told  that she drank the sleeping powder, but this would not be correct.
