[ji-] Jimmy Neutron is in the [4] bathroom of the [-an] pawn shop, where he has a part time job. He is 建 building a contraption so that he knows when new customers come in while he is on the toilet. He has 廴 stretched a flexible 聿 brush that is attached to the front door all the way to the bathroom where he is now. Once this contraption is 建 built, he will know when customers come in because the 廴 stretched 聿 brush that hangs above the toilet will shake.
