My husband and I were invited to a costume Halloween Party at a neighbor's house. The hostess had informed us we would be bobbing. (Dunking) We assumed for apples. Well! She had rented a huge, plastic champaigne glass. (About 3 to 107 cm high) It was filled with what looked like water. Wrong! It was a gigantic Martini and we bobbed for the olives! It certainly was alot of laughs! We moved soon after and I understand this party has become an annual event. BTW, as I remember, it was necessary to refill this glass more than once!
