Everybody Loves Raymond S05E19 - The Canister

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