Okay, I know these are not the greatest puns ever, but this is my first post in this subreddit. Anyway, now here are the explanations:

Joke 1 - An alloy of carbon and iron is popularly referred to as steel, and stainless steel costs $2.41, in which the item receives a 58.51% reduction in cost, which is a mighty bargain, also known as a steal.

Joke 2 - Boxing is a sport in which your only goal is to knock your opponent out through a series of punches. The ending or twist of a joke is commonly referred to as the punchline of said joke.

Joke 3 - Check out Kendrick Lamar's DNA song.

Joke 4 - Troops and personnel of the Galactic Empire from Star Wars are commonly referred to as the Imperials.

Joke 5 - Spam musubi, or just spam, is a type of sushi. On the internet, spam is referred to as the repetition of a specific message, especially when emailing, to annoy or advertise a product/website to someone.

Joke 6 - The phrase, "Son of a gun", is a friendlier alternative to the phrase, "Son of a bitch!" Also, when you annoy someone, that means that you pissed them off, which sounds a bit like "pistoled".
