There was a chap (he was a pro) that played 4 consective holes in -10, that takes some beating, I think he had back to back albatrosses then a pair of eagle's and two of the holes he aced, his card went something 2,1,1,2 against a par of 5,4,3,4. Thats holing 4 consective approach shots. The course was in Chicago.
