For those who remember the original (non-GSN) runs of Card Sharks and Family Feud, you may remember Gene Wood doing the obigatory Contestant and Ticket Plugs.
In addition, both Sharks and Feud also did plugs for people who wished to participate in polls for future questions.
Every so often, they would ask for "specific" people to write in and participate in surveys for future questions.
On these occasions, they would show the "postcard" on the screen with the unusual survey title (to help the sorters at G/T direct it to the proper pile, I assume) along with the address. Example:
"Mad" Scientists
Card Sharks
6430 Sunset Boulevard
Hollywood, CA 90036
Anybody remember the more unusual requests, or your favorite requests for pollsters that Gene, Jim or Richard asked for?
