Person A: "2+2=4"
Person B: "Wrong. It's 5."
A: "How do you figure?"
B: "Any retard knows this. Well, apparently not any retard. Haha."
A: "That's not an argument. Just use a calculator. You'll see that the sum is 4."
B: "I don't have time to jump through hoops for your retarded ad hominem argument, retard. Educate yourself. Later."
A: "Seriously, just take two seconds and you'll see it's 4."
B: "Have you ever made a math mistake in your entire life?"
A: "Uh. Yes?"
B: "Well then your opinion is invalid. Sorry you're all butthurt, but I'm not taking your word for any math."
A: "But it's not an op—"
B: "You make me laugh. You know who else thought 2+2=4? Hitler. Look it up."
