To avoid having to admit that they're using someone else's trademark, Microsoft is now claiming that "Internet Explorer" is a name in common usage -- similar to a car company naming their car "The Car." Who would do such a ridiculous thing? Well, in the latter case, the French. Anyway, Microsoft may have a case. I use it all the time in my own speech:

Verb

The date was going really well until I Internet Explorered.

Adjective

No dear, I think your plentiful back hair makes you look really Internet Explorer.

Interjection

Internet Explorer, Lorena! What'd you have to do that for?

Adverb

You've made it impossible for anyone to get any work done. Quit behaving so Internet Explorably.

Noun

You know who makes a really good Internet Explorer? Netscape!
