[Answer] What is the elephant's nose called?

Step 1 : Introduction to the question " What is the elephant's nose called? "

...

The trunk, or proboscis, is a fusion of the nose and upper lip, although in early fetal life, the upper lip and trunk are separated. The trunk is elongated and specialised to become the elephant's most important and versatile appendage. It contains up to 150,000 separate muscle fascicles, with no bone and little fat.

Elephant trunks have multiple functions, including breathing, olfaction, touching, grasping, and sound production. The animal's sense of smell may be four times as sensitive as that of a bloodhound. The trunk's ability to make powerful twisting and coiling movements allows it to collect food, wrestle with other elephants, and lift up to 350 kg (770 lb). It can be used for delicate tasks, such as wiping an eye and checking an orifice, and is capable of cracking a peanut shell without breaking the seed. With its trunk, an elephant can reach items at heights of up to 7 m (23 ft) and dig for water under mud or sand.

[Answer] The Mason–Dixon Line forms the northern border of which U.S. state?

Step 1 : Introduction to the question "The Mason–Dixon Line forms the northern border of which U.S. state?"

[Answer] Why couldn’t the bicycle stand up by itself?

Step 1 : Introduction to the question "Why couldn’t the bicycle stand up by itself?"

...This joke is another example of a play on words, this time using the homographs "too/two" and “tired” to make the joke. The bicycle was "too tired” (as in sleepy) to stand up by itself, but the bicycle is also literally “two tired” (it has two wheels).

[Answer] What is black, white, and red all over?

Step 1 : Introduction to the question "What is black, white, and red all over?"

...The pun in this joke, of course, is the word red. “Red” and “read” are homophones, which are words that sound alike but are spelled differently and have different meanings. In this case, the joke teller actually means the word “read” because a newspaper is read, but the trick to the question is that the color red is used instead, which sometimes garners an incorrect response.

[Answer] Why did the scarecrow win an award?

Step 1 : Introduction to the question "Why did the scarecrow win an award?"

...This joke makes light of the literal job of a scarecrow: to be out(side) standing in a field of crops. In this case, a small space makes all the difference in the word “outstanding.” Outstanding is an adjective that means exceptionally good, but “out standing” means to literally be standing up somewhere outside, as scarecrows do. Both definitions work together to provide the punchline to this corny joke.

[Answer] Can February march?

Step 1 : Introduction to the question "Can February march?"

...This joke uses the names of the months in order (February, March, April, May) to give a clever answer. February is a month, so it cannot march ("march" as in the verb, not the month). April not only comes next in order but is a common name for a person, signaling that April (the person) "may" (or in other words, "might") march.
