Quick way for de-veining shrimp?

Question

What's a quick, easy, and clean way to de-vein medium-sized shrimp?

Answer 1

Do it when their raw, under running water

Answer 2

There's a tool made for that, but I just use a small, sharp knife. Peel 'em, split 'em, rinse 'em off. *poof* done.

Answer 3

There are 2 veins that need to be removed.  This site has a video showing the technique.  Stay with it.  The opening commercial only lasts  5 to 8 seconds.
