Cowboy Time
9:50am is Cowboy Time. If someone asks you the time, and it is 9:50am, you must tell them that it is Cowboy Time. It's a fair bet that you'll be met with a blank stare, in which case you can launch into the following rendition of the Lone Ranger theme song*
Ten to ten to ten-ten-ten
Ten to ten to ten-ten-ten
Ten to ten to ten-ten-ten
Tennn to ten ten ten

With enough people aware of Cowboy Time, the first lesson of the morning can be turned into a rousing Wild West chorus.
* non-Philistines will of course recognise this as Rossini's William Tell Overture.
