Stunt Idea: Was A Biggie at Wendy's Bigger Than A Vente At Starbucks?

So long, Biggie. Hello, confusion?
Wendy's International Inc. , the No. 3 U.S. hamburger chain, on Friday said it would remove the term "Biggie" from its french fries and drinks, switching to the well known terms small, medium and large.

At rival McDonald's, a 32 ounce soft drink is designated a large. At Wendy's, a 32 ounce drink will now be called medium. Wendy's is also adding a 42-ounce soft drink -- the equivalent of 3-1/2 cans of soda -- as its large. Previously, Wendy's sold a 16 ounce soft drink as a small, a 20 ounce soft drink as medium and a 32 ounce soft drink as Biggie. Now, a 20 ounce drink is a small, a 32 ounce drink is a medium and the new 42 ounce drink is a large. The company will still sell a 16 ounce drink on its 99 cent value menu. At McDonald's, a 16 ounce drink is called a small, a 21 ounce drink is a medium and a 32 ounce drink is a large.

McDonald's famously removed the "Super Size" option from its combo meals after the 2004 release of the film "Super Size Me" -- a documentary in which filmmaker Morgan Spurlock ate nothing but McDonald's fare for a month and tracked his increasingly poor health.

Got it. Quick, now: how many ounces to a Vente at Starbucks? Send your stunt person out to see who's still supersizing, who's not and whose sizes are really bigger/smaller, or get listeners involved via cell phones from fast food spots.
