Maya face Selection

EbonyStallion

In maya 2012, I'm getting a problem. When I select a face, it looks like that, with the vertices highlighted. When I try to extrude from the face, It's completely messed up, I can't quite explain it.
How do I get rid of this pesky setting that I somehow activated?
