This is a photo of a restaurant by my house. The green sign reads "LIVE TACO MAKER." Now, that's all fine and dandy, but honesty, given that the place serves tacos, I would have assumed they had a live taco maker. So I'm not that impressed. Now, if they employed a robotic taco maker, that might be sign worthy, but given that they don't, I think a sign is unnecessary. (Obviously a zombie taco maker would warrant a sign as well.)
