Ennui

Does anyone have any advice for someone suffering from extreme boredom?

Here's my situation. I'm stuck at school (academy). Classes don't help the situation. The last thing I did to relieve boredome was to run around with cable ties (the zippy ones that don't come loose when u tighten them) and tie people and things to random people and things. I feel like making something either extremely cool or extremely funny.

Please post any advice or ideas. Thanx.
