I forgot to mention what ours was.
It was incredibly lame.
They stuck a bunch of snuff cans to the "old gym" (there was an "old gym" that we only used to eat in and a "new gym" that we use as a gym) in the shape of 07. Then in the parking lot, they changed every number they could into 420.
Now, the school just demolished the old gym, so what's the point? I mean, do something better than THAT.
And 420? Extremely juvenile.
