The Shanghai Fugu Agreement (German: Shanghaier Kugelfisch-Abkommen) was a successful 1985 political prank played on the Social Democrats in the German state of Hesse.
The Greens argued that the fugu fish is well known to be a dangerous delicacy requiring specialized chefs who mostly come from Asia. Due to expanding restrictions on work permits restaurants have found it difficult to employ such specialists. The "Shanghai Fugu Agreement" was supposed to provide special regulations for certified fugu chefs internationally.
Was there any specific motivation for this prank?
Were the Greens in any way trying to refer to the Fugu plan, which involved Japan accepting Jews fleeing nazi Germany, which involved Shanghai?
