Going to the "matzah minyan" in the Young Israel of Kew Garden Hills is sort of like getting drunk: Fun and interesting once a year, but debilitating on a regular basis. If you have never experienced this phenomenon I strongly recommend doing so. It is marvelous.
What I like best about that minyan is the guys who leave early. I'm not talking taking your tefillin off during alienu early. These guys are out by the beginning of tachanun.
I know that most of them run supermarkets or other shops that need to be opened very early, but still, it requires a certain type of azus only frum Jews can muster in order to leave halfway through an eighteen minute minyan.
