Your favorite way to warm up and practice?

I know when I was a kid, and it still holds true now, especially when a major holiday is just around the corner, I would always end up figuring out how to play various songs on the Sax regardless of whether or not I had sheet music for it. (My mother never would buy me anything to help me learn the Sax, it was all me doing what I could...)

For instance, whenever I got into a christmasy mood, I'd be working on various Christmas music. I think I just about got Rudolph the Red Nosed Reindeer, Frosty the Snowman, and Jingle Bells down as well as Silent Night. Other times I'd figure out how to play tunes from shows like the classic Sesame Street tune "Sunny Day" (I figured that one out on Bari first since I wasn't liking the sheet music from the teacher much, that would be one of my warm ups to get into the mood of playing each day)

Of course, after doing that my hands would be ready to play scales a bit, but I preferred to do my own little thing. I know everyone else in the band either didn't warm up any at all, or they'd just do long tones which I'd do a bit too, like the first few notes I would blow of the day, but then I would break out into a tune.

I was the same way when it came to when I was learning the Keyboard in fifth grade as well. Does anyone do the same? Oh yeah and I'll be getting my sax very soon. My Bro in Law is going to give me $750, and I plan to spend less than that on the actual sax, and use the remainder for Reeds, a good Neckstrap (As I already have neck problems so I'll have to get a superb one), some music books, a Tuner, Metronome, and maybe even a second mouthpiece.
