My dad gave me an idea about the “light at the end of the tunnel.” It wasn’t quite this gag, though, but I’ll give him credit.
My dad works as a supervisor to big development projects. While making his rounds one day, he struck up a conversation with one of the contractors. It went along these lines:
My dad: “How’s it going?”
Contractor: “Great! We’re finally seeing the light at the end of the tunnel.”
My dad: “Well, let’s hope that light isn’t the headlight on an oncoming train.”
My dad has got a great sense of humor.
