The ultimate truth in advertising?

In a new ad campaign which would be worthy of the Onion, if only it weren’t an actual campaign, the fast food chain Wendy’s has a new advertisement out which pictures two sandwiches clearly containing some sort of meat, with a caption which reads, and I kid you not, “Finally understand the phrase “Whoa, Nelly!”

Obviously this is the answer to “Dude, what’s that meat in the sandwich?”

No wonder poor old Clara Peller kept asking “Where’s the beef?”
