Size

(Rather drunk vaigrant comes in)

Drunk: Tell me, what does a double K look like?
EM: It depends on the back size
Drunk: But what does it look like?
EM: It depends on the back size as cup size scales. So a 28KK will be smaller than a 40KK
Drunk: oh (walks out and shouts to someone outside) SHE SAID IT SCALES WITH THE BACK SIZE!
