"Fire Safety Seminar" joke
A fire official was giving a fire safety seminar to a group of factory employees. Demonstrating the proper way to operate an extinguisher, he told the group, ""Pull the pin like a hand grenade, then depress the trigger to release the foam."
Later, he selected a blonde female employee to extinguish a controlled fire in the parking lot. Standing with the extinguisher in her hands, she was so nervous that she forgot to pull the pin.
The instructor hinted, "Like a hand grenade, remember?"
In a burst of confidence, she pulled the pin and hurled the extinguisher into the blaze.
