I'm in the family way

One day the Mexican maid announced to the Yuppette that she was
quitting. When asked why, she replied, "I am in the family way." The
Yuppette was both surprised and shocked and asked who it was. The maid
replied, "Your husband and your son." This time, the Yuppette was
horrified and demanded an explanation. "Well," the maid explained, " I
go to the library to clean it and you husband say, 'You are in the
way.' I go to the living room to clean and you son say 'You are in my
way. So I'm in the family way and I quit."
