Leet o'clock 

A time of day that is worshipped especially by computer geeks, leet o'clock occurs every day at 13:37. Due to differences in the display of hours on digital clocks, this recurring event has traditionally enjoyed more popularity in English-speaking countries outside of North America.

George: Look, it's leet o'clock!
