Depends on degree of boredom... if its like in class boredom which is the worst then I look at peoples faces and try to come up with which animals they resemble. Also, I look for things out of place in classrooms, listen for te letters teachers can't pronounce, and I read all the quotes on the wall. When I am not being tortured by pointless droning of teachers: I hike, skinny-dip,do random dares in Walmart, throw parties(I threw a penis party and 70s throwback last year), raquetball, take roadtrips for a day and see where I end up, watch random music videos and try to immitate the dance moves, download music, randomly ask someone out, poll strangers on embarrasing questions such as masteurbation habits ... basically anything stupid and pointless thats not quite jack-ass level but has bypassed the 6th grade version of truth or dare.
