Tunnel Rats 

U.S. military personnel whose job is to crawl through enemy tunnels in search of the Viet Congs.

The tunnel rats were American and Australian infantry soldiers whose task was to carry out underground search and destroy missions during the Vietnam War. The Viet Cong guerrillas had built a complex system of tunnels in which they hid themselves and their weapons when they were under attacks. They were extremely dangerous, with numerous booby traps and enemies lying in wait.

Tubing In Aruba 

An expression a typical Harold McGee would use when asking his students to stop daydreaming about being a thousand miles away. Often used during important lectures.

When you're sitting there sweating bullets on the AP exam, I'm going to remember this day, how you didn't hear a word I said. You were off tubing in aruba, a thousand miles away.
