Well the same Warlock that transformed his sheep into the corn and his cabbage into a goose. Could magic him across the river.

Unlikely, but total guess xD + Show Spoiler + The bullet is fired as he jumps, so the gun flails in the air and the bullet hits the rope, cutting the cord. He falls into the water? (It says he is on a rock... a large rock = cliff? with an overhanging tree perhaps...) which extinguishes the flames and he vomits out the poison after having drank some seawater. Seems like the only answer to me unless I'm missing something (possibly to do with the name... is it an alternate scenario that I'm not thinking about?)

how many places are there on the earth that one could walk one mile south, then one mile west, then one mile north and end up in the same spot? to be precise, let's assume the earth is a solid smooth sphere, so oceans and mountains and other such things do not exist. you can start at any point on the sphere. also, the rotation of the earth has nothing to do with the solution; you can assume you're walking on a static sphere if that makes the problem less complicated to you.
Hint: + Show Spoiler +think you've figured it out? do you know that there's more than one? in fact, there are more than two. also note that walking north from the north pole (or south from the south pole) is illogical and therefore does not enter into the problem. all normal assumptions about directions will be used.

This one kept me up for days
3 guys walk into a hotel and put down $10 each totalling $30 to get a room for the night. The manager hands over the key and the guys take the elevator up. Minutes later, the manager realized that the 3 guys overpaid - the actual price should have been $25. Therefore, he gives $5 to a boy asks him to take the $5 back up to the 3 guys. On the elevator, the boy wonders how 3 people can split $5, so he takes $2 and puts it in his own pocket and distrbutes the remaining $3 one dollar per person.
But wait, if each person just received a dollar back, it would technically mean that they each paid $9 instead of $10. 3 x 9 = 27 plus the $2 the boy stole = $29. What happened to the missing dollar?

this was in the pic thread within the past 2 weeks. + Show Spoiler +the two dolars that the boy stole are part of the 27 paid, so those two are being double counted. If you just want to look at where the original 30 dollars go, man 1 has 1, man 2 has 1, man 3 has 1, theif has 2, cash regester has 25. 1+1+1+2+25=30

The extra $2 doesn't get added to $27, it's subtracted.

Going trough door 2 you will have to go trough water with a electric current going trough it because of a electric cable lying in the water at the far end of the room.
Going trough door 3 you will have to fight a group of very agressive bears. You can't fool them.
At the end of each room there is a door. If you make it to the door, your life will be spared.

The answer is false lol
the missing dollar didn't go anywhere because it does not exist you are not adding the 2 dollars to both sides of the equation properly, you are adding it to one side twice . The easiest way to visualize this is two sides of an algebraic equation . one side we will call the register side , the other the customer side . it all adds up, there is no extra dollar . 25 (at the register side) 25 in register plus 2 in the bellboys pocket = 27 plus 3 dollar refund = 30 . now if we add it up from the other side(customer side ) . 10 x 3 = 30 - 3 (refund ) =27 . 9x3=27 plus 3 = 30 . the only answer is : 25+2+2=27 is false

Here is one. I hope my translation of the question will be easy to understand.:
A guy that works for the census bureau visits a house. The father of the house opens the door.
Census guy: How many children do you have? Father: I have three daughters. Census guy: Could you please tell me the exact ages of your daughters? Father: The product of their ages is 72 and the sum of their ages is our door number. Census guy: But, this is not enough information! Father: My oldest daughter loves horses. Census guy: Thank you.
How did he find the ages of the daughters and what's the house number?
Tip: + Show Spoiler +The guy sees the house number, but we do not know it.

While I am at it, here is another one:
A courier is carrying a sack full of marbles. We know there were 300 marbles of five different colors in the sack. The courier though, while passing a river, slips the sack off of his hand and lets some marbles fall into the river. We know the amount of marbles that fell are at least 100. He tells us that out of the remaining marbles in the sack, 1/3rd of them are white, 1/4th of them are red, 1/5th of them are blue, 1/7th of them are yellow, and 1/9th of them are green. However, we also know that the courier is not so good with math and we are sure that one of the information he has given is wrong.
How many marbles of each color remained in the sack and how many marbles fell into the river?

census guy + Show Spoiler +factors of 72 are 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, and 72. so we have 1 1 72 = 74 1 2 36 = 39 1 3 24 = 28 1 4 18 = 23 1 6 12 = 19 1 8 9 = 18 2 2 18 = 22 (oh god im going to kill myself) 2 3 12 = 17 2 4 9 = 15 2 6 6 = 14 3 3 8 = 14 3 4 6 = 13 all the sums except 266 and 338 are unique, so it had to be 266 or 338 if the guy didnt know "oldest" means it's not 266, so the census guy knows its 338 actually did this myself, so forgive me if i missed anything
