I've been wanting to make a Gaijin 4koma joke for long time, and looky here, I finally shat one out lol.
I Love Solly's expression. Nuff said.
Actually I should explain:

Okay this is from the computer game Team Fortress 2, guy on top is Spy and he's wearing a cloak (the mask with the woman's face drawn on) and he tricks people with the illusion of being some buxon babe. (But yeah.. he's a guy with a mask)Bottom panel is the great Gaijin reaction with some of the team's members.
Right to Left: Scout, Medic, Demoman, and Soldier.
