re: What's your favorite television commercial - any time period.

Pizza Hut made a post-Thanksgiving commercial back in the 90s I believe that was hysterical.

A guy is sitting at the head of his dining room table, waiting for his wife to bring in each post-Thanksgiving successive night's turkey leftover surprise dinner - to the tune of "12 Days of Christmas" with the husband's face getting more disappointed each night :)
- Turkey Tetrazinni, Turkey Pie, Turkey Stew,
Turkey Loaf, and, for the 5th (in tune with "5 Gold Rings) 'Flaming turkey wings' and they show the wife from the neck down walking in with her face hidden by a platter of wings on fire.

Then the shot edits immediately to the husband literally gagging at the sight of turkey wings on fire and he nearly gets sick and gets up from the table.

The tagline is 'tired of turkey leftovers, call Pizza Hut.'
