I find it very hard to believe the story about the Hamburger. Unless I am mistaken the "Whopper" originated with Burger King or a similar American company and was so called because it was quite large compared to those of the opposition.

What relationship is there between bodies in East London being washed over three times by the tide and an American "Delicacy"?

Where does this information come from Anne? Sounds like a bit of fakelore.
