Blogs can be fatiguing to maintain (sans revenue) until something like this comes along. Mascot Roommate. These guys prank their poor roommate who has a job promoting a coffee shop.
It takes the fun out of it to think it might be staged, but there's certainly tips that would suggest that. One thing's clear to me- it's not an ad campaign. Coffee Bean wouldn't sanction this (some of it's crude) and they certainly wouldn't serve the clips on a Mac account. So whether it's staged or not, we can conclude that the real prank is on the store and its customers.
That said, this would make a helluva viral ad campaign, wouldn't it? I think if I was the PR guy for Coffee Bean, I'd have our lawyers send a "cease and desist" letter. And if I was the head of marketing, I'd give 'em a check, pull down the "over the top" content (Mascot thrusting pole), and put some viral wind behind it.
