Michael:
I can name you three holes in a row that total a par of 12 that can top those three at Brae Burn for shortness by a ton. These three in a row aren't the first three but for combined shortness I don't think you could top the so-called "Quirky Corner" (6-8) on Merion West.
They total about 666 yards, a significant number indeed. 
Tom, isn't the total par of 6-8 at Merion West 11, not 12?
6 is a par 3, 7 and 8 are par 4s, no?
To get to 666 yards, par 12, you'd have to have some awfully short par 4s.
