Here's perhaps the most unlikely entry yet in the recent spate of ads showcasing buttocks of every kind. In this U.K. Fallon spot, the Cheestring character swims ashore and lasciviously shakes himself dry in a bit that's reminiscent of Bo Derek's cheesy antics in 10. It's a bid to promote the brand's "Cheestrings Spaghetti" line extension, and here the Chees-guy is wearing a very form-fitting bathing suit. You might call it … a string-cheese bikini! He's got super-tight glutes (like a finely aged cheddar), but those who eat this stuff regularly might wind up with thighs and derrieres of the cottage-cheese variety.
