I like scavenger hunts. I've participated in one or two, and provided the items on the list don't involve doing anything illegal, too embarrassing or too impossible (University of Chicago, I'm looking at you), I look forward to participating in future ones.
I missed one last weekend, the Impossible Montreal scavenger hunt, which was actually far from it.
Three teams participated, making videos and taking pictures to complete their tasks. As an example, here are each of the three groups performing their own haka:
There were other fun things, like doing a Rick Mercer-style rant about Rick Mercer or eating as many steamies as possible. Another one was Peter Mansbridge/Wendy Mesley slash fiction, that's just too good an idea not to link to, so here they are: The Sub-Librarians, The Flying Feltchions, #swag (bonus pointless references to Mutsumi Takahashi, Debra Arbec and Lori Graham in the latter).
The full list is here (PDF, after some humourously-crafted rules). Each of the participating teams used Tumblr accounts to upload pictures, video and text of their exploits, which you can find here:
