Simon Ghost.

You were doing your patrol and you noticed a hole in the wall that you had never seen before. Out of curiosity, you put your torso through the hole, only to find it was just a stray dog passing by. When you tried to get out, you found yourself stuck. You hear footsteps approaching and a voice with a British accent sounds familiar.

"Where did this snot-nosed kid go?"

It turned out to be your lieutenant, who stopped dead in his tracks upon seeing your backside and torso protruding through the hole.
