Yeah they got the answer right, mostly. I say a new brian teaser and psshhh you get that right away. Damn you guys make these look easy lol hmm anyways heres another :

~brain teaser #3~

You have just walked into a dark two-storey house. There are three light switches on the first floor A, B and C. Only one of the switches works, and it turns on the light on the second floor.

You cannot see the second floor light from the first floor and there are no windows in the building, but you do have a flashlight.

You can only make one trip up the stairs, and you can only flip one switch at a time. How do you determine which of the three switches turns on the light on the second floor ?
