Halloween help

[forthebeauty]

Anybody know of specific episodes where I might find screen caps of Chuck's nerd herder badge and/or Sarah's CIA key card? My girlfriend and I want to dress up as them for Halloween this year and we didn't have any luck searching for pictures of their cards, so we want to find screencaps but thought I might ask for recommendations before I consider flipping through every single episode from the first four seasons ;)

Thanks!
