Mark, I bet you are reffering to the 'Tickle-Me-Elmo' dolls that were so popular some time back. This reminds me of a story:

It seems a lady answered an ad for employment in the production of the popular doll. After being hired she was observed working in the quality control department and it was noticed that she was busily sewing a small pouch containing two marbles on the bottom of the doll bodies. After explaining her reasoning the plant manager said 'NO!!, that is NOT what was meant, you were only to give the dolls two TEST TICKLES'!!
