Good People,
I love the really bad jokes section. Oh the joy. But I encountered a bad joke that I just don't get. Could one, sigh, explain the punchline for me. Here's the joke:

Henry Lang grew up in Kansas, part of the most wealthy and influential family in the area. Everyone around knew of the Langs, and eventually, in gratitude for all that the family had done for the area, the townsfolk erected a huge sign in front of the train station, saying, "Welcome on behalf of the Langs." One day, Henry, now in his forties, returned to the area, and he was shocked to see that the townsfolk had taken down the old Lang sign.

Thank you,
Eug' 'ene
