Tricky! Well I probably have a stupid answer but here it goes:

Switch one light on and peek through the keyhole to see whether it's on or not? and do this repeatidly until you see the light is switched on and then you open the door and enter...?

That's a good answer, but the door has no keyhole

Oh, hmmm...interesting, confusing and a good riddle!

Swicth on a switch. Make a cup of tea, or maybe try practising loud farts. Either way, wait. Long enough for the bulb to get hot. That is, of course, if you've chosen the right bulb.

Switch off the switch and switch on another one, and immediately enter the room.

- If the light is on, then it's obviously that switch you've just switched on.
- If the light is off, check to see whether the bulb is hot. If so, then the correct switch is the first one you switched on.
- If the light is off and the bulb is cold, then it's third switch you're after.
- Fart in front of your friends to show them the practice and progress you've made.

LMAO. Yep, you've got it, Cloone! You can go now.

Woohoo!!!

How many times can you cut a 1.5 cm slice of bread from a whole loaf?

You can cut into it an infinite number of times. No matter how many time you cut into it, there will always be some left.

That is... incorrect!!!!!

Wait. I read it wrong lol. You can cut into it 16 times. A whole loaf of bread is 22.5 cm long, and 4 cuts divides something into 5 slices. So 16. I think lol?

That's more like it.

However..... it's still incorrect!

15 <EDIT> Using the idea above

Nnnnnnope

well u can slice the slices inot 1.5 cm there for 16 x how ever many times you can cut the slice i dont feel like doing the math so have fun lol

Nothing to do with division - the length of the loaf is irrelevant

lol then im going to say 1

Darn it, thought my brilliant math stategy (ahem) woulda pulled it off Lol

dr_fedx is right!!! 1 it is. After you take one slice from a whole loaf, it is no longer a whole loaf!!! Once is all you can do it without irrevocably, irreversibly and irreparably changing the condition of the loaf from a whole one to an incomplete one. Much like asking "How many times can you get it on with a virgin?" Once; after that, she ain't no virgin no more!!!

Your go, Doctor

A man was found dead in his study. He was slumped over his desk and a gun was in his hand. There was a cassette recorder on his desk. When the police entered the room and pressed the play button on the tape recorder they heard: "I can't go on. I have nothing to live for." Then there was the sound of a gunshot. How did the detective immediately know that the man had been murdered and it wasn't a suicide?

i edited it cause the other one was too easy lol there ya go

Because someone rewound the tape. The dead man couldn't have done it.

EDIT: If I'm right, someone else can have my go because I won't be here - sorry!
