America can't handle authentic codpieces

Telegraph:

The stars of Wolf Hall, the BBC’s new period drama based on the novels of Hilary Mantel, have disclosed they have been issued with “smaller”-than average codpieces, out of respect for viewers' sensibilities. 

Mark Rylance, who stars as Thomas Cromwell in the forthcoming BBC series, said programme-makers had decided on “very small codpieces” which had to be “tucked away”. 

He suggested allowances had been made amid concerns about the taste of modern audiences, particularly in America, who “may not know exactly what’s going on down there”.

Now what would make them think that?
