Kreml High episode "Too Fat":
Here we can see Crazy Ivan and Tony beating and rubbing Tvetov Nato's
stomach with a "Fläskpinne" (Porkstick) so he will get
thin enough to f*ck his girlfriend.
what I am trying to say is: Don't use a bottle - use a stick with some
feathers on instead.
...but seriously: I don't think that you (or Tvetov) need to use a stick
(or a bottle) at all.
