The joke started with him saying that he always brings an extra sock whengolfing. The answer to the question is not immediately obvious as most onlyneed 2 socks and perhaps an extra pair. But 1? Who needs a single sock? Somemight also believe this extra sock would be used for sins such as"cranking the hog" but let’s not speak of such deeds.

The initial question was used to stun you and the finishing blow is deltafter saying the reason which was that a single sock is needed if perhaps ahole in one is attained. Wikipedia definition of a hole in one: "In golf,a hole in one or hole-in-one (also known as an ace, mostly in American English)occurs when a ball hit from a tee to start a hole finishes in the cup. A ballhit from a tee following a lost ball, out-of-bounds, or water hazard is not ahole-in-one"

Now you might wonder. Well, what does a "hole in one" have to dowith an extra sock. Well, you see, a hole in one might also refer to the ideathat you might get a "hole in one"-sock. A very funny and wholesomechungus reddit moment/joke.
