Java Programmers Wear Glasses

Ah, the language war in coffee mug form. The punchline here is that Java programmers need glasses because they don't "C#" (see sharp). Classic programming dad joke that hits harder after your fourth cup of coffee and fifteenth NullPointerException of the day.

It's the kind of mug you hide when clients visit but secretly cherish when debugging legacy code at 11pm. The irony is that most of us need glasses regardless of our language preference—staring at poorly indented code for a decade will do that to anyone.
