Certainly not where Eureka came up with the Vibra-Groomer. I had a friend who carpeted his whole house but would always buy a little Eureka Princess with one of these. I told him not to worry about trying to find this atachment after I put it away. I don't know why he would not buy an upright.
Now don't read this if you have delicate sensibilities:
When I worked in housewares at Rich's in Atlanta, we started selling Panasonic small appliances like the blenders (very interesting designs), blow dryer and the Panibrator, an large, interesting, but certainly not suggestively shaped body massager with a body like a long white column and a vibrating end that was of a larger circumference with a ribbed drum shape. One morning a phone call was answered by one of the sweetest women, of a certain age, who had recently begun working during the Christmas season. She began the conversation very normally, listening while the lady on the other end asked if the Small Electrics Department sold vibrators. Sarah demonstrated excellent product knowledge by explaining about the two different types; the type that you put on the back of your hand for a deep manual massage and then the Panasonic style. She paused and then this look of absolute horror came over her face. She was in such a state of "high horror" that when our male manager walked by, she just pushed the receiver at him, forcing him to take the call. He finished the call quickly and sent one of the other ladies to find and comfort Sarah. The caller's final request was something to the effect of,
"No, not that type. I want one shaped like your penis." I don't know which of the last two words freaked her out more. The other ladies talked about it among themselves and discussed it with a couple of us guys in the department, but the Southern males were far too gallant to mention it to Sarah.
