Let’s Get Down To Business, To Defeat The Puns

(My friend and I are studying for our upcoming exams. A few semesters before this, I changed majors from Chemistry to English.)

Friend: *singing* “Let’s get down to business, to defeat the huns.”

Me: *giggles*

Friend: “What?”

Me: “I just realized that after all my time in math and science, how did I miss the chance to say, ‘Let’s get down to business, to defeat the sums?’”

Friend: “Get out.”
