Kathryn – Cosmo does not comment on Nazi dog antics. However, it sounds like this guy got exactly what he wanted. His Htler T-shirt and Sieg Heils didn’t get enough attention so he taught his dog this Nazi salute nonsense. Of course, I should say that Cosmo does do something similar when I say “Hi Five!” But with the exception of Jerry Seinfeld and his schtick about the “Heil Five,” I’m unaware of any connection.
