Haha Startvalve, that's hilarious.
But seriously, I actually have wondered, as UAL747 asked, how fast the exhaust from a typical jet engine is travelling upon exit from the jet. I once asked a professor about this, and got an answer of around 2000 ft/sec, if i remember correctly, which is obviously extremely fast. I could probably look in a fluid dynamics book and get an answer, or just run some quick equations, but it's winter break, and my books and my brain are thankfully 2500 miles away.
"Two and a Half Men" was filmed in front of a live ostrich.
