Try Screencaps

Note: I took all of these screen caps myself from DVDs. It was a LOT more work than I anticipated. If you use them a "Thank you" and a link to my site would be appreciated. I'm not going to say "no" to anyone who asks. Feel free to use them, that's what I made them for! Just let me know.
You may notice the Alt tags on many thumbnails when you hold your mouse over them. Thanks to BJ, Irony, Steph, Stan, and Ryo for the suggestions!
