Are SNG's the most annoying form of poker?

Ahhhhh.. 25 games into the 100 SNG challenge. I've never before felt so frustrated playing poker. I normally play cash games. There are a lot less all ins, and far less push/fold poker. So I'm not used to constantly getting ejected from tournaments when my AA and KK all ins are called by random cards like 7 2 which then time after time after time.... beat my hands. WTF. The tournament I played in a few moments ago. I was ejected in fourth place (3 places paid) when my AA was trounced by the mighty 3 5 offsuit.

How do people play these things for a living. They must have the best tilt control ever, the patience of a saint.
