1. Progress must be blogged. Slam, applaud, give away the ending, whatever, just blog it.
2. Though incidents like Streisand yelling "Shut the f*%k! up!" to a heckler are wildy theatrical, concerts do not count.*
3. It doesn't matter how many times you go to Mamma Mia!, you can only count a show once in a single year.
*Kritzer-ish and Wainwright-like recreations of concerts are excepted. Those count. (-Patrick)
