The eternal divide between programmers and mathematicians in one perfect meme. In programming, "2!=2" is checking if 2 is not equal to 2 (which is false, so "No"). But in math, "2!" means factorial of 2, which equals 2, making the statement true ("Yes"). This is why programmers should never date mathematicians. Dinner conversations would be a nightmare. "Hey, could you pass the salt?" "No, because that's syntactically ambiguous and I'm interpreting it as a boolean expression."
