Two twins are lying next to a king and a queen in a large room. Yet, there are no adults and there are no children in the room. How is it possible?

The twins, the king, and the queen, are all (types of) beds.

A man is sitting in his cabin in Colorado. Three hours later he gets out of his cabin in Texas. How is this possible?

The man is a pilot and he is sitting in his airplane cabin.

A bus driver was heading down a street in Colorado. He went right past a stop sign without stopping, turned left where there was a “no left turn” sign, and went the wrong way on a one-way street. Then he went on the left side of the road past a cop car. Yet, he didn’t break any traffic laws.

Why not?

The bus driver was not driving his bus, he was walking.

Two very short friends, John and Jack, were living together in an apartment. Since they used to lose their apartment key very often, they decided to leave it on top of the door frame when they leave home. In order to reach the key, John was climbing on Jack’s shoulders and thus taking it down from the frame. However, John was the taller and the heavier guy of the two. Why didn’t Jack climb on his shoulders instead?

The reason is that as being taller, John also had longer arms. If Jack climbed on John’s shoulders, he wouldn’t have reached the key.
