By far the most entertaining thing to come out of the Rally to Restore Sanity (save the rally itself) were the signs that clever Stewart/Colbert fabricated and brought with them. Some of my favorites:
Reddit has the most exhaustive list of signs that I’ve been able to find.
Also, check out Linda Holmes’ write-up of the event, which uses a “Highs” and “Lows” format that I plan on employing more often for my live coverage of events.
[UPDATE: The Washington Post now have an excellent selection of photos in the form of a user-submitted gallery. Gawker also has a great gallery]
