Georgetown’s famous Healy Tower has seen its clock hands go missing -- yet again.

According to Georgetown University Spokesperson Rachel Pugh, nobody with the school's Facilities Department removed the clock hands.

Police say they were taken sometime over the weekend.

Healy's clock hands were last swiped in 2005, but they have a long history of being stolen, going all the way back to 1966.

The 2005 theft was attributed to two students at the time, reports the Georgetown Hoya.

"When I learned of the tradition of stealing the Healy clock hands freshman year and reading various publications about the history associated with the tower, I decided that I eventually wanted to contribute to the survival of the tradition before I graduated," [student Andrew] Hamblen told the Hoya at the time.

Healy Hall is a historic building on the Georgetown campus, constructed from 1877 to 1879.
