"Fat" as a description of a person is as medically valid as "stupid". That is to say, not at all. "Overweight", "obese", and others are actual medical terms that have real definitions, quite unlike "fat".
Agreed. All instances of the word "fat" are used by the writer. The only instance of a medical professional saying something that would warrant the word "fat" is Dr. Rolph, who is quoted as saying "overweight."
I'm also a big fan of odd time signatures, especially those that change. A great example of this is Dream Theater's "The Dance Of Eternity": https://www.youtube.com/watch?v=9ftRhsvvfBw In ~6 minutes, there are 104 time signature changes, largely between 3/2, 3/4, 4/4, 5/4, 6/4, and 7/4.
Another great one is Radiohead's "Pyramid Song": https://www.youtube.com/watch?v=zbKQPqs-cqc It's in (3+3+4+3+3)/16 (depending on how you interpret it), and it's one of the hardest songs to count, as the last note is swung and deceptive. But it's a great composition.
Pyramid Song is in 4/4. If you only listen to the piano part, then you might think it's odd, but when written in 4/4 the notes are just dotted quarter notes and half notes. The drum part is more revealing of the 4/4 time signature.
I've been on IRC non-stop since 1997; it's where the majority of my closest friends and I keep in touch. I also run an IRC channel for the class I teach, and it's the primary communication means for most students.
As for YC, there's the ##startups channel on Freenode, unofficially.
Actually, the reason that I very much remember this is that my mom has never let me live it down! (It was my brother's toy computer, which cost a fair amount, for our family.)
Edit: And I never said that I was successful, but simply that my goal was understanding. It was most certainly my goal (it was something that repeated through childhood, many, many times), but it was equally certainly a failure.
