Happy something-or-other last minutes of Decemberween!
Homestar's bedroom clock has made its sole appearance in
Homestar Presents: Presents. In addition to being seen in the toon, at the end it is used to display the number of minutes of
Decemberween left (until midnight on December 26 to be exact). It runs off your computer's time and says "It's Over" should the time run out.
