A van der Merve joke.
The Cape Province asks for bids on a tunnel through Table Mountain. Germany bids $50 million, the U.S. bids $75 million, and van der Merwe bids $100.
"But, van der Mere, how can you dig that tunnel for $100?"
"Ach, man, I'll start on one side, my son will start on the other, and we'll dig toward each other."
"What if you don't meet in the middle?"
"Then you'll get two tunnels for the price of one."
