The fight for the emergency exit seats

On most airlines, the emergency exit row seats often offer plenty of extra room either on the sides, legroom or both. I believe airlines should set another restriction to passengers who want to sit there. Passengers who are taller than 6' 1 should get priority to those seats. All the gate agents has to do is pull out some measurement device, either a tape measure or some kind of fixed markings on the Jetway door. It really pisses me off when I see passengers sitting in those seats who are shorter than 6 feet, so much I just want to beat them. They don't deserve those seats. So find ways to annoy them when you sit either in front of or behind them. Consult the last post about annoying passengers in subtle ways part 1.
