Even A Broken Clock Is Right Twice A Day

Ah, the classic Japanese Yen hack! Some poor soul wrote a currency conversion function that divides the exchange rate by 100 only for JPY. Why? Because the Japanese Yen doesn't use decimal points (1 USD ≈ 150 JPY), so someone "fixed" it by dividing by 100... which is completely wrong and will utterly destroy your financial calculations. But hey, that one time when the exchange rate is exactly 100, the code will accidentally work! Just like that broken clock... right twice a day.

Ctrl+Z Not Found: The SQL Massacre

OH. MY. GOD. The absolute HORROR of running an SQL UPDATE without a WHERE clause! 😱 That moment when your stomach drops to the floor as you realize you've just modified 37,052 rows instead of the ONE you intended to change. And the worst part? There's no magical Ctrl+Z to save your career from this database apocalypse! Your face transitions from "I'm a database wizard" to "I should probably update my resume" faster than you can say "rollback transaction" (which you FORGOT to use, obviously). This is why database professionals drink heavily. 💀

Maybe I Can But I Won't

The eternal struggle of every CS graduate - spending four years learning algorithms, data structures, and computational theory only to be reduced to "the tech person" who can supposedly fix any electronic device within a 50-mile radius. That smug little smirk in the final panel says it all. It's the universal "I could write you a sorting algorithm that would make Donald Knuth weep with joy, but diagnosing why your laptop makes that weird clicking noise? Yeah... I'm suddenly very busy with important computer science things." The cognitive dissonance is exquisite. We're simultaneously expected to understand the deepest mysteries of computation AND why your printer only works when Mercury isn't in retrograde.
