So a Klingon, Hirogen and a Jem'Hadar Walk Into a Bar...

... who walks out alive?

It depends on which one is being played by Clint Eastwood.

I recon the Klingon and Jem'Hadar go head on with the latter being the stronger one. However, just before the final blow the Klingon pulls out his d'k tahg and kills the Jem'Hadar. As the Klingon stands up and shouts/waves/klingon ritual/etc of victory, he gets shot in the back by the Hirogen who was hiding under the table :P

What if he plays all three of them?
