If you felt like you were floating away on Sunday afternoon, you weren't alone!  You were in the company of many, many other people that got punk'd.  Aaannnnd, may very well be a little loony.

Unfortunately, I found out AFTER the fact, that the claims that due to an unusual planetary alignment, earth's gravity would momentarily fail enough so that if someone were to jump in the air at precisely 12:47pm, they would not immediately return to the ground, were a hoax.
