This is especially funny to me, given I was just reading about psycho squirrels on crevette‘s journal.
I am upstairs, studying for the Pharm lecture exam tonight when there is a noise right over my head. thuddathudda-thuddathudda-thweee!
I look up in time to see a squirrel go by the window, as Newton is proved aright again. He (the squirrel, not Sir Isaac) looked very distressed. I get up and look out the window and towards the ground. There is no squirrel. He is nowhere to be seen. Evidently, it is quite shameful (for a squirrel) to miss the tree they’re leaping onto from your roof. He’s probably hiding somewhere.
The Process 
Hahahahaha! I saw a squirrel miss a very high branch at ACC once. He fell about 20 feet, bounced, sat there a moment, and than ran off. He seemed embarrassed.
It’s like when a cat runs into a glass door or something. They stalk off looking like, “I meant to do that!”
So he jumped from the roof and missed the tree, ha.
Yeah; I’ve a large oak(???) right outside my office window. It is about a three foot or so jump from the roof. He leapt, missed and disappeared. I swear to Rudy that he hung in the air for a moment (ala Wile E. Coyote) looking distressed before dropping out of view.
