So BillMonk is a convenient way of informally keeping track of how much your friends owe you. What's frightening is that one of the two developers is a Clint lookalike. You can spot the difference because the BillMonk imposter is not wearing a Hawaiian shirt.
Sorry I couldn't find a better comparison photo, but this is the only one I could quickly find online. A Google image search turns up this photo and one comic dedicated to Staley.
Update, 9:12 PM: I've made a graphic comparing the two photos directly, in case the links ever up and die on us.
