Well, I must not be schizophrenic, b/c I actually had to think about it for a minute. But here's the answer:
You turn on one swith for 15 minutes or so and then turn it off. Turn on a second switch and then go into room #2. The bulb that is on is controlled by switch #2. The hot, dark bulb is switch #1. The cool bulb is #3.

Riddle me this:
When Nita Bath the waitress at the Dirty Duck Restaurant brought Detective Sergeant Hans Zupp his usual cup of coffee, she had something. special to tell him.
"Those three fellows at the far table are up to something," Nita whispered. "I saw one of them slip a revolver to one of the others he called Eddie. By their accents, I'd say they're all foreign. One of them English, one's an Australian and I think the other one is French."
"Which is which?" asked the Detective.
"The one on Eddie's right is the Australian, and the Frenchman is on the Englishman's right."
"Which one is Eddie?" asked the Detective, but Nita was called away before she could answer, and the three men were getting up to leave.
The detective followed the men outside, made an excuse to get them into conversation and--having already worked out for himself what Eddie's nationality was--soon discovered who was carrying the gun.
Which one was Eddie?
