Poll: Who left the joint in the parking lot?

I was over at the Northern Attack Watercooler forums, posting my theory that in the upcoming episode, Drug Testing, it will be Jan who left the joint in the parking lot, and Michael tries to protect her from an overzealous Dwight.

Then I thought: wow, what a good idea for a poll. :)

So who do you think left the half joint in the parking lot? Cast your vote here!

I’ll close the poll before the episode airs. Then we’ll see how savvy we really are… ;)
