If you're looking for a site that collects some of the dumbest things people tween to various company brands, then look no further than http://dumbtweetsatbrands.tumblr.com/. You've got tweets to Pepsi, Hostess, Dominos, Arbys and more.
A couple of the best ones include @moderatelycool tweeting @dominos to "Stop charging so much for your gradually shrinking pizzas, or I'll start charging for the BJ's I give your delivery guys" as well as @hasseimtweets telling @mcdonalds that "by serving illegal immigrants you take their money and for that we salute you but feeding them is another story jerks".
