We here at uTest's marketing team enjoy a good interal practical joke - especially if it's at the expense of the sales team - and we're soliciting new ideas.
What are the best humerous uses of Marketo you've done, or heard of, to this end?
Update:
v01 - One of our good natured reps loves receiving email alerts when he gets new leads. We've threatened that we're going to blow up his inbox so we finally added some logic so ten minutes after he receives a new lead "his manager" (aka well formatted Marketo email) forwarards him the original prospect email with a comment asking him to follow up immediately.
