Everybody Loves Raymond - Season 5 Episode 19 -

Tempers flare when Marie accuses Debra of not returning a borrowed canister that holds sentimental value and Debra insists that she has already given it back. Debra is then horrified when she discovers that she does indeed still have the canister in her possession. With Ray and Robert's reluctant assistance, she concocts an elaborate scheme to get rid of the evidence, rather than confess to Marie that she was wrong and her mother-in-law was right all along.
