"Emergency Course" joke
A blonde, brunette, and redhead all go into a building to take an emergency course. After a few minutes of introductions, the instructor of the course starts to talk about fire.
"Wherever you see a fire, you need to call 911, imediately." After an hour or so of the lecture, the brunette makes an excuse to get out of there, by saying she needs a drink. 2 minutes later she comes running back in, with fire fighters behind her, and she yells, "There's a fire!"
They all run out, and after a few minutes the fire fighters come back out, and say, "We can not find a fire." The blonde suddenly screams out "WHAT ARE YOU TALKING ABOUT" she gestures towards the redhead, "THE FIRE IS ON HER HEAD."
