"Hi, does this wrag smell of chloroform?"
I had a friend whose older (late 20s) brother somehow got some chloroform, I don't know if he made it, stole it or bought it or what his intention were.
But his younger brother found him passed out in the loungeroom, clutching a rag soaked with it and instead of calling for help (he thought his brother was napping, stoned, or drunk) he smelt the rag. Bad idea, wakes later and a third guy, one of his friends who was over at his house, is unconscious as well.
Edit: Funny thing is chloroform is mild carcinogen, so we had this joke that when someone was being abducted they were like "oh not chloroform, I could get cancer!". As if that was their only concern about the situation.
