The funniest part of the game so far is having to protect the Burger Town, which looks suspiciously like a Burger King. It's hysterical to hear officers yelling "bogies inside the Burger Town" and "we must protect the Burger Town!"
I imagine that in Infinity Ward history books, children will read about the day that the brave men and women of our country sacrificed themselves to protect the Burger Town of Northern Virgina. Much blood was spilled on the extra value menu that day.
In fact, if you are amongst a squad of Army Rangers, it is not uncommon to hear servicemen valiantly charge into battle crying out in one voice: "REMEMBER THE BURGER TOWN!"
