The slowest man on the street contest

Moshe and his friend Peter stood and argued whose car is faster: Moshe's silvery FJ Cruiser or Peter's smooth new Lexus Hybrid. Another friend, Daniel, joined the discussion and being an experienced lawyer (complex-deal settler between ego-maniacal corporations) he told both parties that he will give $100 to any of them whose car will come last after going around the block. Hearing this, Moshe jumped into the car and put the pedal to the metal. He won. How?

A Drinking Puzzle

As a young manager, Moshe was known for his relaxed attitude of "No drinking at work" policy. Once he found a completely full bottle of an unlabeled liquid, smelling like alcohol under one of the desks.

Whose grass is greener?

Who has the greenest grass on our street? This unannounced competition has been going on forever. Each of the neighbors pretends to go for a walk with his dog or child and carefully reviews other's grass: color, height and weed count. Then, he quietly sneaks back home, spends a day searching the Internet and tries to overdo the neighbors' grass. As a result the grass in the house number 32 is greener than in house number 16, which has less weed than house number 9, which is cut more frequently than house number 17. Who does the most land labor?

When is it going to explode?

One morning Moshe and his friend decided to make homemade Root Beer. They put some powder in the bottle, added yeast and water. They tightly closed the cap on the bottle and were observing this cool growing substance. The instructions said that every cell is dividing by half every minute creating two new cells of the same size as the original. With this speed, by 10pm that day they would manage to grow half a bottle of this substance from only one cell. How long would it take until this bottle fills up and explodes?

Beware of Halloween

One past Halloween, Moshe was captured by a local children's tribe that demanded candy. Unprepared and candy-less, Moshe tried to confuse the kids by offering them a choice of chores he could do for them. He told them, I will tell you one statement. You will decide, if this statement if true or false. If the statement is true, I (Moshe) will put on a ballerina costume and go around the neighborhood with you gathering candy and then give all the candy to you. If the statement is false, I will sit and guard your candy supply for the next 10 hours or as long as it takes for you to finish Trick-o-treating. Then Moshe told kids his statement. Surprisingly, they did become confused and just let him go. What statement did Moshe make that forced the kids to spare him?

Armani suit on a single salary

Three friends are dying to get the Armani suit from the latest fashion show, but neither could afford to pay what the suit is offered for. The first friend, Daniel, who is famous for his preference for first class travel over expensive suits, is saying: "If each of you two will give me half of what you have, I will have enough to buy the suit. We could then share the suit proportionally to our investments." The second friend, Alex, stately and broad shouldered, is saying: "If each of you will give me one third of what you have, I will also have enough to buy this suit. We can then share it proportionally to our body sizes." Then the third friend, who happens to be Moshe, said: "If each of you two will give me just one fourth of what you have, I could buy this suit. We could then split the suit according to our investments." Who has most money of these three friends?
