Last night at my house, a girl went to use the bathroom. After a few minutes, I started to wonder what she was doing.
"What is she doing in there?" I asked. "Is she doing blow?"
A few moments later, she came out of the bathroom, and the incident was briefly forgotten. Ten minutes after that, I went into the bathroom.
"That girl was NOT doing blow in the bathroom!" I declared.
HOW DID I KNOW THAT SHE WAS NOT DOING BLOW IN THE BATHROOM?
A) I searched the cabinets and confirmed that I have no suitable mirrors on which to do blow. Therefore she must not have been doing blow at all.
B) The bathroom smelled like poo, which I deduced to mean that she had been taking a poo in the bathroom rather than doing blow.
C) There was a syringe, a burnt spoon, a short length of rubber tubing, and a small spatter of blood on the floor, which I deduced to mean that the girl had been "riding the H-train" rather than doing blow.
D) I recalled that the girl had no nostrils, which would have prevented her from doing blow in the traditional way.
