OK, the classic is "Hi, Bob" from the Newhart show. If you aren't familiar, people on the show said "Hi, Bob" a lot and some viewers made a game out of it, where every time someone said "Hi, Bob," you took a drink (of beer or whatever you're into). People playing the game (usually college students) would repeat "Hi, Bob" whenever they heard it, then take a drink.
I've adapted that game to some current shows, and thought it might be fun to see if others are doing the same thing, or just get some new ideas even if you haven't thought of it until now. I usually don't actually drink when these shows are on, but just get some amusement out of finding words/phrases that get repeated a lot and seeing which shows would make good drinking games. It is fun, though, if you're with a group of people to give it a try, even if you're just drinking Pepsi.
Here are my top three:
3. Survivor - "Alliance" This word is obviously used a lot on the show.
2(a). The Bachelor - "Connection" This word is repeated a lot on the show, but not as much as...
2(b). The Bachelor - "Amazing" Bachelor Bob almost turned me into an alcoholic by saying this word over and over and over. It was truly an amazing experience. Other Bachelors and Bachelorettes say it a lot, too. If you haven't noticed, you'll be amazed the next time you watch the show.
1. The champion, never to be dethroned...Househunters (on HGTV) - "Nice" This show is about people looking at homes with a real estate agent, and it seems that every other word is "nice." "This is a nice home, and the location is very nice. Ooh, that floor is nice! Yes, it sure is nice, etc., etc." If you actually had a drink every time you heard the word "nice," you'd be passed out long before the show was over!
What else have you got?!?
