Originally named the "Love Boat Drinking Game." Very fun, with a high buzz factor. Supplies: people, beer, and a tv show with enough different characters for each player.
Before the show starts, each player chooses what character s/he will play. For example, if watching the "Love Boat," someone will play the Captain Stuebing, one will play Gopher, another the Doctor, another Isaac, and even someone will be the Pacific Princess.
