There were an electrician and a plumber waiting in line for admission to the Home Show. One of them was the father of the others son. How could this be possible?
Common Wrong Answers
“The electrician is the father and the plumber is the son.”
This guess assumes a traditional father-son relationship, which contradicts the riddle's hint about one being the father of the other's son.
“They are both brothers.”
This guess overlooks the relationship context provided in the riddle, which specifically mentions a father-son dynamic that cannot exist between brothers.
“They are friends waiting in line.”
While it's possible for friends to wait in line together, this guess fails to address the familial relationship stated in the riddle.
