Best Classic Riddles Ever

A sponge is full of holes, which allows it to absorb and hold water. Even though it has many openings, it can still retain a significant amount of liquid.

An echo is the correct answer because it is a sound that is heard when sound waves bounce off a surface and return to the listener. The more an echo is repeated, the softer it becomes as the sound waves lose energy with each reflection. Although an echo cannot be seen, it can be heard, making it the best fit for the given description.

The answer "When it has a hole in it" suggests that even though a man's coat pocket may appear empty, there could still be something in it if there is a hole in the pocket. This implies that the item in the pocket may have fallen through the hole and is no longer visible from the outside.

The man's horse was named Tuesday, so when it is mentioned that he left two days later on Tuesday, it means that he left on the same day of the week that he arrived, not necessarily the same calendar day.

A doughnut is the correct answer because it is a type of nut that does not have a shell. While a peach, a mango, and the brain are all types of nuts, they do have shells. However, a doughnut is a pastry that is shaped like a ring and does not have a shell like other nuts do.

A shadow fits the description because it is only one color (usually black or dark), but it does not have a specific size as it can change depending on the angle and intensity of light. It appears to be stuck at the bottom as it is always connected to the object casting it, yet it can easily move and "fly" when the object moves. Shadows are present in sunlight but disappear in the rain. Shadows do not cause harm and do not have the ability to feel pain.

The correct answer is "Today". The question is asking for the difference between yesterday and tomorrow, and the answer is "Today" because it is the current day between the two mentioned days.

When homework is done at school, it is no longer considered homework because the purpose of homework is to be completed outside of the classroom. When it is done during class time, it becomes classwork instead.

The question is asking which clock works best, the one that loses a minute a day or the one that doesn't work at all. The correct answer is "The one that loses a minute a day." This is because a clock that loses a minute a day is still functional and can be adjusted to keep accurate time, whereas a clock that doesn't work at all cannot be used to tell time. 

The King went to the dentist to get a new crown. This implies that the King needed a replacement for his crown, which could mean either a dental crown or a royal crown. However, since the question is about a visit to the dentist, it can be inferred that the King needed a new dental crown to be placed on one of his teeth.
