The JavaScript one is funny. To be honest they should have picked a different name for JavaScript since it has nothing to do with Java.
>In 1995, after 10 days of work, Brendan Eich created a scripting language for browsers. He called it Mocha. The language was renamed several times over the course of just a couple of months, and was eventually given the name we know today, JavaScript. Brendan originally wanted to add support for the Schema programming language to the Netscape browser, but his superiors wanted the language available in their browser to be more like the then popular Java [1].
