Can Anyone Suggest Some trivia Themes?

Hey, All... I host a Trivia/Quiz night in Guangzhou, China. It's at a Western Bar Called the Tavern Bar and Grill. I have been doing it for 1 year now. That's 52 weeks of Quiz's. 4 Different categories per night. That's 208. That's a lot of topics. I have repeated themes like NAME THAT TUNE, MOVIES, BEFORE THEY WERE STARS... all set to a different theme so they are all not the same. Can anyone suggest Themes, Topics, Ideas? Recently I have done themes like... SEX, DRUGS, ROCK AND ROLL. EAT, DRINK AND BE MARY. EARTH WIND AND FIRE. THE GOOD THE BAD AND THE UGLY.

I have exhausted Movies and Music (unless set to a specific theme). LOGOS. Before they were stars.

ANY HELP WOULD BE APPRECIATED.

THANKS...
