I didn't know classes could be 4 hours long. Happy Birthday! If the slides are online, you should get blazed and just sit in the back and draw pictures
I had one of those on a cake once
and as the candles faded and the battery died out
all you could hear was a the tune of 'happy birthday'
me and my friends just left it there to go empty because we couldn't turn it of and when we came back in I heard the most creepy, deformed versions of that song ever...
That thing is evil. It sings to you, happily, cheerfully... and then it melts and sounds creepy as **** . It stops for a few seconds, and then half an hour after you throw it out, you can hear it slowly singing to you again from the trash can.
