I found this one funny from Battlefield: Bad Company, when you have to rescue your squad then head back to the coast to find shelter, and instead you find that guy you'd kidnapped.
President - "What? I'd never side with those imperialist pigs! They kidnapped me."
Bad guy - "Since you didn't get the gold, I'm going to tax your land instead. You're country is now mine... Kill him."
President - "Oh no, please, don't. I beg you."
Sweetwater - "So. What now?"
Sarge - "Follow my lead"
*all charge in, firing and bringing down soldiers*
Sarge - "Don't worry, President, you're safe."
President - "Ah, imperialist pigs, very nice."
It must be the accent that makes it funny. one second he hates them, but typically he suddenly loves them! hahah!
