Can Blender unbridge (unloop) a mesh? I am following a coffee cup tutorial where I have to bridge two extrusions. I did that but the edges are intersecting giving crappy results.

I saved AFTER the bridge - so if I have to recreate it I will - but was hoping to learn HOW to fix. 

Attached are two images showing the problem. Thanks!
The bridge edgeloops has an option that can help. The operator options are available by pressing F6 and can also be found at the bottom of the tool panel on the left T.



The twist amount defines which top vertex bridges with which bottom vertex.
