"Blondes Working At Company" joke

Their are two blondes working at a company together. The rest
are redheads and brunettes. One day a blonde came in and
started yelling "I'm a light, I'm a light!" The boss went over
to her and and told her that if she yelled that again she would
get fired. So the next day the blonde came in yelling "I'm a
light, I'm a light!" The boss went over too her and told her
that she was fired. So she started to pack her bags and her
other blonde friend was packing her bags too. The boss went
over to her and said "Why are you packing your bags I fired
your friend not you?" "I know", said the blonde "but how am I
supposed to work without a light?"
