I don't have any hilarious breast related anecdotes,
however I am aware of the acute embarrassment that can be caused when making smalltalk in polite company, you suddenly find yourself short of a comic term for German breasts. Therefore I propose a handy cut out and keep list. You can never have too many so please add your own.

Teutonic titties
Fraulein's funlumps
Baden-Baden bazookas

Munchengladbaps?

It does if you like the word rack. To my mind, it's too hard-sounding to be used to describe the squashy smashingness of breasts.
