Khmer. Wat Pho?
We were visiting the Wat Pho temple in Bangkok. As I am sure you know, the Wat Pho temple was built several hundred years ago by people who were part of the Khmer kingdom.
This gave rise to the following exchange between me and my twenty-year-old nephew.
Me: "Hey, Austin"
Him: "Yeah."
Me: "Khmer."
Him: "Wat Pho?"
Both: "Ha ha ha ha ha."
Everybody else: nothing but eye rolls.
The more often we did this little exchange, the funnier it got.
