Checklist, 2008
On June 27, 2008, Whysoserious.com was updated to include a montage of various Joker-related websites, and a checklist with links to every major Joker trail in the ARG. The accomplished tasks are crossed out on the list.
- When the page was first discovered, the list had three tasks that were not crossed out. All items are now crossed off, which implies that the game has ended.
 July 3
After the end of the Operator trail, item 12 is crossed out with a link to Whysoserious.com/Operator and the date 7/1, meaning there are now only two tasks left.
 July 10
Task 13 is crossed out with a link to Whysoserious.com/Bamboozle and the date 7/7, leaving "leave a big mark" as the only task remaining.
 July 11
Task 14 is crossed out with a link to Whysoserious.com/Kickingandscreening and the date 7/9, meaning that the ARG has apparently ended.
 July 13
Included in the montage are images of various ARG elements, linking them to that particular page. The elements include newspaper clippings, bowling shoes, a personality quiz, Gotham map, phone directory (with every URL and phone number of the ARG-related Gotham businesses), a cake infested with maggots, the Whysoserious.com/Happytrails ad, the Atasteforthetheatrical.com ad, a vandalized Joker card, a Jokerized portrait of Lincoln, bloodied Polaroids of people wearing Joker makeup, and a Jokerized dollar bill.
 Police Reports
Clicking on items 1, 2, 3, 5, 7 and 8 brings up confidential GPD reports about each of the events. Transcripts of these reports can be seen on each event's respective page.
