Space Cadet! AKA: TGIF

I've been battling a horrible case of Space Cadet-edness all week, I'm very sorry to say.
I know what I should be doing (like working, for example) but instead I choose to sit and stare at my computer, and maybe blink on occasion, while my brain makes the sound of a skipping record, an engine that won't turn over, or a broken hard drive (it alternates... no, really.)
I don't really know why I have this affliction! So many reasons, I suppose, and all I want to do is go play outside.
The Sister-In-Law-To-Be has a similar post on her blog. Is it the weather? Whatever it is, we need some excitement!
Any advice?
